It’s simple to imagine that Robert Woo was outlined by the accident that took away his capacity to stroll.
Actually, the day of his accident—14 December 2007—was a turning level. Woo, an architect engaged on the brand new Goldman Sachs headquarters in New York Metropolis, hadn’t attended his firm’s vacation celebration the night time earlier than, and that morning he was the one one within the trailer that served because the construction-site workplace. He was bent over his laptop computer when, 30 flooring above, a crane’s nylon sling gave method, sending about 6 tonnes of metal plummeting towards the trailer. The roof collapsed, folding Woo in half and smashing his face into his laptop computer, which smashed by his desk.
“I used to be aware all through the entire ordeal,” Woo remembers. “It was an out-of-body expertise. I may hear myself screaming in ache. I may hear the voices of the rescue staff. I heard one firefighter say, ‘Don’t fear, we’re attending to you.’” The rescue staff hauled him out of the rubble and obtained him to the emergency room in 18 minutes flat; with one lung crushed and the opposite punctured, he wouldn’t have lasted for much longer. In these frantic early moments, a physician instructed him that he could be paralyzed from the neck down for the remainder of his life. He remembers asking the docs to let him die.
Woo merely couldn’t think about how a paralyzed model of himself may proceed residing his life. Then 39 years outdated, he labored lengthy hours and jetted world wide to oversee the development of skyscrapers. Extra essential, he had two younger boys, ages 6 months and a pair of years. “I couldn’t see having a life whereas being paralyzed from the neck down, not with the ability to educate my boys the way to play ball,” he remembers. “What sort of life would that be?”

However in a Manhattan showroom final Could, Woo confirmed that he’s not outlined by that accident, which left him paralyzed from the chest down, however with using his arms. As a substitute, he has outlined himself by how he has responded to his damage, and the brand new life he constructed after it.
Within the showroom, Woo transferred himself from his wheelchair to a 80-kilogram (176-pound) exoskeleton swimsuit. After strapping himself in, he manipulated a joystick in his left hand to rise from a chair after which proceeded to stroll throughout the room on robotic legs. Woo’s steps have been brief however clean, and he clanked as he walked.
This exoskeleton, from the French firm Wandercraft, is among the first to let the consumer stroll with out arm braces or crutches, which most different fashions require to stabilize the consumer’s higher physique. The battery-powered exoskeleton took care of each propulsion and steadiness; Woo simply needed to steer. The cumbersome equipment had a backplate that prolonged above Woo’s head, a big padded collar, armrests, motorized legs, and footplates. Strolling throughout the room, he gave the impression to be half man, half machine. On the opposite facet of the showroom’s plate-glass window, on Park Avenue, a child strolling by along with his household got here to a lifeless halt on the sidewalk, staring with awe on the cyborg inside.

The amazement on the boy’s face was paying homage to Woo’s younger sons’ response after they noticed a photograph of Woo attempting out an early exoskeleton, again in 2011. “Their first remark was, ‘Oh, Daddy’s in an Iron Man swimsuit,’” he remembers. Then they requested, “When are you going to start out flying?” To which Woo replied, “Nicely, I’ve obtained to discover ways to stroll first.”
The title of exoskeleton superhero fits Woo. He’s as soft-spoken and mild-mannered as Clark Kent, with a smile that lights up his face. But the energy beneath is simple; he has constructed a brand new life out of sheer dedication.
For 15 years, he’s been a take a look at pilot, early adopter, and clinical-study topic for probably the most outstanding exoskeletons underneath improvement world wide. He positioned the primary order for an exoskeleton that was authorized for residence use, and he realized what it was wish to be Iron Man round the home. All through all of it, he has given the businesses detailed suggestions drawn from each his architectural design expertise and his consumer expertise. He has formed the know-how from inside it.
Saikat Pal, a researcher on the New Jersey Institute of Know-how, in Newark, met Woo throughout medical trials for Wandercraft’s first mannequin. Like so many others within the discipline, Pal shortly acknowledged that Woo introduced rather a lot to the desk. “He’s a super-mega consumer of exoskeletons: very enthusiastic, very athletic,” Pal says. “He’s the proper topic.”
By pushing the know-how ahead, Woo has paved the best way for hundreds of individuals with spinal wire accidents in addition to different types of paralysis, who are actually benefiting from exoskeletons in rehab clinics and of their houses. “Our bionics program at Mount Sinai began with Robert Woo,” says Angela Riccobono, the director of rehabilitation neuropsychology at Mount Sinai Hospital, in New York Metropolis, the place Woo grew to become an outpatient after his accident. “We’ve a plaque that dedicates our bionics program to him.”

It’s a becoming tribute. Woo’s post-accident life has been marked by victories, frustrations, deep love, and one devastating loss, and but he has continued to commit himself to bionics. And whereas his imaginative and prescient for exoskeletons hasn’t modified, expertise has reshaped what he expects from them in his lifetime.
Lengthy earlier than Woo ever stood up in a robotic swimsuit, he had developed the habits of thoughts that may later make him an unusually perceptive take a look at pilot.
Woo has at all times been a builder, a tinkerer, a fixer. Rising up within the suburbs of Toronto, he put collectively mannequin kits of battleships and airplanes with out trying on the directions. “I simply put issues collectively the best way I assumed it could work out,” he says. He skilled as an architect and in 2000 joined the Toronto-based agency Adamson Associates Architects, a job that quickly had him touring to Europe and Asia to work on company high-rises.
Adamson focuses on taking the gorgeous designs of visionary architects and turning them into sensible buildings with elevators and bogs. “A lot of the design architects don’t actually have a clue about the way to construct buildings,” Woo says. He preferred fixing these issues; he preferred reconciling lovely designs with the cussed actuality of building. That expertise for understanding a construction from the within and recognizing the failings would show important later.
After his accident, Woo had two main surgical procedures to stabilize his crushed backbone, which required surgeons to chop by muscle tissues and nerves that related to his arms. For 2 months, he couldn’t really feel or transfer his arms; there was an opportunity he by no means would once more. Solely when sensation started creeping again into his fingertips did he enable himself to think about a special future. If he wasn’t paralyzed from the neck down, he thought, perhaps extra of his physique might be introduced again on-line. “My focus was to stroll once more,” he says.
Woo was discharged in March 2008 and went again to his New York Metropolis residence. He was nonetheless bedridden and required around-the-clock care. He doesn’t very similar to to speak about this subsequent half: By Could, his then-wife had moved again to Canada and filed for divorce, asking for full custody of their two kids. Woo remembers her saying, “I can’t take care of three infants, and one in all them for all times.”
It was a darkish time. Riccobono of Mount Sinai, who met Woo shortly after he grew to become an outpatient there in 2008, remembers the despondent look on his face the primary time they talked. “I wasn’t certain that he wasn’t going to take his life, to be trustworthy,” she says. “He felt like he had nothing to dwell for.”
Angela Riccobono of Mount Sinai Hospital (left) credit Woo with jump-starting the hospital’s bionics program; a plaque within the division of rehabilitation medication acknowledges his function.
But Woo harbors no animosity towards his ex-wife. “If we hadn’t separated and gone by the custody listening to, I don’t suppose I’d have gotten this far,” he says. To win partial custody of his kids, Woo needed to turn into unbiased. He needed to get off narcotic ache drugs, regain energy, and discover ways to navigate life in a wheelchair. He needed to present that he now not wanted fixed nursing, and that he may care for each himself and his boys.
There have been milestones: studying the way to get again into his wheelchair after a fall, studying to drive a automobile with hand controls, studying to handle his physique because it was, not because it had been. The most important change got here when he reconnected along with his highschool sweetheart, a vivacious girl named Vivian Springer. She was then dividing her time between Toronto and New York Metropolis, and she or he had a son who was nearly the identical age as Woo’s two boys. Springer had labored in a nursing residence and knew the way to change the sheets with out getting him off the bed; she was at the moment working in human assets and knew the way to take care of insurance coverage corporations. “You wouldn’t imagine how a lot stress it lifted off of me,” Woo says. Over time, they grew to become a household.

As soon as Woo had that basis in place, Riccobono witnessed a profound change. “He went from specializing in ‘what I can’t do anymore’ to ‘What’s nonetheless doable? What can I do with what I’ve?’” At Mount Sinai, Woo remembers asking his physician Kristjan Ragnarsson, who was then chairman of the division of rehabilitation medication, if he would ever stroll once more. “His response was, ‘Sure, you possibly can stroll once more,’” Woo remembers, “‘however not the best way you used to stroll.’”
First Steps in an Exoskeleton
As quickly as he had regained use of his arms, Woo had began googling, on the lookout for something that would get him again on his toes. He tried rehab tools just like the Lokomat, which used a harness suspended above a treadmill to allow customers to stroll. However on the time, it required three bodily therapists: one to maneuver every leg and one to regulate the machine. It was a far cry from the unbiased strides he dreamed of.
A number of years in, he realized about two corporations that had constructed one thing radically completely different: exoskeleton fits for folks with spinal wire accidents. These prototypes had motors on the knees and the hips to maneuver the legs, with the consumer stabilizing their higher physique with arm braces. Woo desperately wished to attempt one, though the know-how was nonetheless experimental and much from regulatory approval. So he took the thought to Ragnarsson, asking if Mount Sinai may convey an exoskeleton into its rehab clinic for a take a look at drive. Ragnarsson, who’s now retired, remembers the request nicely. “He definitely gave us the kick within the behind to get going with the know-how,” he says.

Ragnarsson had seen a long time of failed makes an attempt to get paraplegics upright, together with “inflatable clothes product of the identical materials the astronauts used after they went to the moon,” he says. All these gadgets had proved too tiring for the consumer; in distinction, the battery-powered exoskeletons promised to do a lot of the work. And he knew the CEO of Ekso Bionics, a Berkeley, Calif.–based mostly firm that had constructed exoskeletons for the navy. In 2011, Ekso introduced its new medical prototype to Mount Sinai.
The day got here for Woo’s first stroll. “I used to be excited, and I used to be additionally scared, as a result of I hadn’t stood up for nearly 5 years,” he remembers. “Standing up for the primary time was like floating, as a result of I couldn’t really feel my toes.” In that first Ekso mannequin, Woo didn’t management when he stepped ahead; as a substitute, he shifted his weight in preparation, after which a bodily therapist used a distant management to set off the step. Woo walked slowly throughout the room, utilizing a walker to stabilize his higher physique, his steps a symphony of clunks and creaks and whirs. He discovered it mentally and bodily exhausting, however the effort felt like progress.

Riccobono was there for these first steps, with tears operating down her face. “I remembered how he regarded the day I first met him, so defeated,” she says. “To see him rise from the chair, to see him rise to a standing place, to see how tall he was, to see him take these first steps—it was lovely.” Ragnarsson noticed clear advantages to the know-how. “Any kind of strolling is nice physiologically,” he says. “And it’s an incredible enhance psychologically to face up and look somebody within the eye.” Woo remembers hugging his companion, Springer, and for the primary time not worrying about operating over her toes along with his wheelchair. I first met Woo a number of days later, throughout his third session with the Ekso at Mount Sinai.

Later that very same yr, at a Division of Veterans Affairs (VA) hospital within the Bronx, Woo obtained to attempt a prototype of the world’s different main exoskeleton: the ReWalk, from the Israeli firm of the identical identify (since renamed Lifeward). VA researchers, led by Ann Spungen, have been eager to find out if exoskeleton use had actual medical worth for veterans with spinal wire accidents. Woo was a part of that medical trial, for which he had greater than 70 strolling classes, and he’s since been in lots of others. However he remembers the primary VA trial with probably the most gratitude. “Dr. Spungen’s first exoskeleton medical trial actually turned issues round for me,” he says.
Over the course of the trial’s 9 intense months, Woo says he noticed noticeable enhancements to many sides of his well being. “By the tip of the trial, I eradicated about three-quarters of my remedy consumption,” he says, together with narcotic ache drugs and drugs for muscle spasms. He grew fitter, with much less physique fats, extra muscle mass, and decrease ldl cholesterol. His circulation improved, he says, inflicting scrapes and cuts to heal extra shortly, and his digestion improved too. The outcomes Woo skilled have typically been borne out in analysis research on the VA and elsewhere—exoskeletons aren’t simply good for the thoughts, they’re good for the physique.
Enhancing Exoskeletons From the Inside
Through the VA trial, Woo started to think about exoskeletons not as miraculous machines, however as works in progress.
Pierre Asselin (proper), a biomedical engineer, labored with Robert Woo throughout medical trials of exoskeletons. He says Woo was at all times pushing the boundaries of the know-how. Robert Woo
Pierre Asselin, the biomedical engineer coordinating the VA’s examine, watched contributors reply very in a different way to the tools. “These gadgets aren’t the equal of strolling—you’re drained after strolling a mile,” he says. He notes that later fashions of each the Ekso and ReWalk enabled customers to provoke every step by software program that acknowledged after they shifted their weight. Asselin provides that the cognitive load is “like studying to drive a guide transmission automobile, the place at first you’re actually struggling to coordinate the clutch and the brake.” Woo picked it up instantly, he remembers.

Woo grew to become a useful companion, Asselin says. “After we first began with the gadgets, there was no coaching guide. We developed all of that by collaboration with Robert and different contributors.” Woo pushed the boundaries of the know-how, Asselin says, whether or not it was seeing what number of steps he may tackle one battery cost or simulating a failure mode. “He’d say, ‘What occurs if I used to be to fall? What can be the method to getting up?’”
Woo approached the ReWalk the best way he had approached buildings in his earlier life: He regarded contained in the construction and located the weak factors. An early mannequin left some customers with leg abrasions the place the straps rubbed—a small damage for most individuals, however a severe threat for somebody who can’t really feel a wound forming. Woo steered higher padding and stronger belly helps to redistribute the load. He additionally hated the heavy backpack that carried the battery and pc, so one afternoon he grabbed an outdated pack, lower off the straps, and rebuilt it right into a compact hip-mounted pouch. Then he snapped photographs and despatched them to the corporate. The subsequent mannequin arrived with a fanny pack.
Robert Woo despatched detailed design sketches as a part of his suggestions to exoskeleton engineers. Robert Woo
Typically his fixes have been extra bold. One Ekso unit that he used at Mount Sinai stored shutting down after half-hour. Woo felt the hip motors and located them scorching to the contact. “I mentioned, ‘Can I take away these? I’m going to make a very fast repair, okay? Give me a drill and I’ll put a few holes in it,” he remembers telling the therapists, proposing to create a DIY warmth sink. He wasn’t allowed to switch the prototype, however a yr later the corporate launched improved cooling across the hip motors. “There’s a Robert Woo design on this machine,” one therapist instructed him.
Eythor Bender, who was then the CEO of Ekso, referred to as Woo to thank him for his suggestions and invite him to spend per week at Ekso’s headquarters. “There was no lack of engineering energy in that constructing,” says Bender. “However typically if you work with engineers, they overlook essential issues.” Bender says Woo introduced each design expertise and lived expertise to his weeklong residency. “He instructed the engineers, ‘Guys, this needs to be one thing that folks truly wish to put on.’”
Ekso Bionics CEO Eythor Bender and Mount Sinai doctor Kristjan Ragnarsson have been each readily available for Woo’s early trials of the Ekso machine. Ragnarsson says he noticed bodily and psychological advantages of exoskeleton use. Robert Woo
The longer Woo examined, the additional forward he began considering. With motors solely on the hips and knees, each exoskeleton nonetheless required crutches. Add powered ankles, he instructed the Ekso and ReWalk groups, and the fits may steadiness themselves, releasing the consumer’s arms. However Woo was forward of his time. “They mentioned they weren’t going to try this. They weren’t going to alter their entire platform,” he remembers. Years later, although, hands-free exoskeletons like these from Wandercraft would emerge constructed round precisely that precept.
When the Exoskeleton Got here Residence
By the mid-2010s, Woo had pushed the know-how so far as he may in clinics. What he wished now was to make use of an exoskeleton at residence.
That milestone got here after ReWalk’s exoskeleton grew to become the primary to win FDA approval for residence use in 2014. ReWalk engineers nonetheless bear in mind Woo’s assistance on the ultimate exams for that personal-use mannequin. It was the tip of Could in 2015, remembers David Hexner, the corporate’s vice chairman of analysis and improvement. “He mentioned, ‘Guys, that is nice. I’m going to purchase it.’”
Woo was the primary buyer to purchase an exoskeleton to convey residence, paying US $80,000 out of pocket. His insurance coverage wouldn’t cowl the price, however he was in a position to make the acquisition partly due to a authorized settlement after his accident. The house-use mannequin got here with a requirement that the consumer have a minimum of one companion who was absolutely skilled in working the machine. In Woo’s case, that meant that Springer realized to swimsuit him up, realign his steadiness, and assist him if he fell.
On supply day, two SUVs drove as much as a resort down the road from Woo’s apartment within the Toronto space. The technicians hauled two large containers right into a resort room and assembled his private exoskeleton. They took Woo’s measurements, made changes, checked the software program. This newest model might be managed by both weight shifting or tapping instructions on a smartwatch, and Woo had the app prepared. He examined out every little thing within the resort room, signed off, after which the technicians drove his robotic legs to his residence.
That was the beginning of his golden interval with the ReWalk—much like the thrill many individuals expertise with a brand new piece of train tools. “I used it daily for a number of hours, after which I began logging what number of steps I’d performed,” Woo says. “My final rely was in all probability simply barely over one million steps,” he says, with half of these steps taken in his residence unit and half in coaching packages and medical trials.
The ReWalk was the primary exoskeleton accessible to be used outdoors the clinic. Robert Woo’s ReWalk arrived in two massive containers. ReWalk engineers assembled it in a resort room, and Woo tried it out within the hallway earlier than taking it residence. Robert Woo
Tristan, Woo’s eldest son, remembers doing laps along with his dad within the apartment’s underground parking storage whereas his dad was coaching for a 5-kilometer race in New York Metropolis. Tristan admits that he had beforehand been embarrassed about his dad, however coaching for the race shifted one thing for him. “I used to be so used to not wanting to inform people who my dad was in a wheelchair, however then I shared his ardour for the coaching,” he says. “When folks would come as much as us, I’d inform them about it.”
The ReWalk may flip atypical moments into small engineering tasks. On weekends, Woo would take his boys to the golf course behind their apartment and convey a baseball. He had rigged two holsters to the edges of the swimsuit so he may stash a crutch and stand on three factors (two legs and one arm) whereas he pitched or caught. Throw, swap crutches, catch. On the day of his accident, he by no means thought such a scene can be doable. However with the exoskeleton, it grew to become simply one other design downside to unravel. “It’s somewhat extra work. It’s not excellent,” he says. “However in the long run, you continue to get to do what you need to do—which is play ball together with your sons.”
Tristan, now a university scholar, says he didn’t notice on the time how onerous his dad labored to make these mundane actions doable. “Reflecting on it now,” he says, “he has formed nearly each component of my life, and he positively is my hero.”
However even throughout that golden stretch, the ReWalk had a method of asserting its limits. On occasion it could freeze mid-stride and require a reboot—a small technical hiccup in idea, however a significant issue when there’s an individual strapped inside. As soon as, when he was strolling on his personal within the parking storage (with out his mandated companion), the swimsuit glitched and went into “sleek collapse” mode, reducing him to a seated place on the bottom. Woo needed to ask safety to convey his wheelchair and a dolly.
He had imagined the exoskeleton can be most helpful within the kitchen. Woo likes to prepare dinner, and he had pictured himself standing on the range, trying down into pots, and transferring simply between counter and sink. The fact, he discovered, was extra sophisticated. “It’s truly very time-consuming and troublesome” to prepare dinner in an exoskeleton, he says.
Making ready a meal meant first rolling by the kitchen in his wheelchair to collect each ingredient and utensil, then transferring himself into the ReWalk and transferring himself into place on the counter, stopping at simply the fitting second. “That’s after I fell as soon as,” Woo says. “I collided with the counter after which misplaced my steadiness and fell backward.” If all went nicely, he’d lean both on one crutch or the counter to maintain his steadiness whereas he labored. But when he’d forgotten to seize the vinegar from the cupboard, he’d have to enter stroll mode, crutch over to it, and determine the way to carry the bottle again to his workstation.
Sitting unused in Robert Woo’s residence, his ReWalk exoskeleton displays each the promise and the boundaries of early gadgets. Robert Woo
Step by step, he stopped attempting. The swimsuit, which he’d as soon as worn daily, spent extra time sitting idle within the hallway; like so many deserted treadmills and stationary bikes, it gathered mud. A part of the rationale was the exoskeleton’s sensible limitations, however a part of it was a stunning improvement: In 2024, Vivian was recognized with an aggressive type of breast most cancers. She died in November of that yr, on the age of 54.
Woo was scheduled to start a brand new spherical of medical trials for the Wandercraft home-use exoskeleton that month. Within the aftermath of Vivian’s demise, he postponed his classes and questioned whether or not he would ever return. “On the time, I assumed, ‘What’s the purpose?’” he remembers.
He did return, although. “He simply rolled up, proper into my workplace,” says Mount Sinai’s Riccobono. “He nonetheless had Vivian’s field of ashes on his lap. That’s how recent it was.” Woo introduced the field into a gathering of spinal wire damage sufferers and shared the story of shedding the love of his life. And he instructed them that he heard his spouse’s voice in his head daily, telling him to get again to work. As soon as once more, he was determining the way to transfer ahead with what he had.
How Shut Are We to On a regular basis Exoskeletons?
Within the Wandercraft showroom final Could, Woo steered towards the door to the road, technicians flanking him like spotters. The slope all the way down to the sidewalk was barely an inch excessive, however everybody tensed. He shifted his weight and took a step ahead. The swimsuit halted mechanically. He tried once more—step, cease; step, cease—because the swimsuit stored detecting the slight decline and a security function kicked in. The Wandercraft isn’t but rated for slopes of greater than 2 %, and even the light pitch of Park Avenue was sufficient to set off its safeguards. When he lastly reached the sidewalk, Woo broke into a smile. A person within the again seat of a stopped Uber leaned out his window, filming.
Throughout testing of the Wandercraft exoskeleton, straps precipitated an abrasion on Robert Woo’s leg, which he documented as a part of his suggestions to the corporate. Robert Woo
Woo had not too long ago accomplished seven classes with the Wandercraft on the VA hospital and had been impressed general. However on the showroom, he rolled up his pants leg to disclose an abrasion on his shin, the results of a strap that had worn away a patch of pores and skin throughout an extended strolling session. He would later ship Wandercraft a nine-page evaluation with photographs and a know-how want checklist, asking the corporate to work on issues like padding, variable strolling speeds, and deeper squats.
Wandercraft’s engineers relish that sort of consumer suggestions, says CEO Matthieu Masselin. Exoskeletons are a much more troublesome engineering downside than humanoid robots, he explains. “You principally have two methods of equal significance. You already know concerning the robotic—it’s absolutely quantified and measured. However you don’t know what the individual is doing, and the way the individual is transferring inside the machine.”
Since Woo started testing exoskeletons 15 years in the past, each the know-how and the market have made strides. ReWalk and Ekso gained FDA clearance for medical use within the 2010s, and each now promote home-use variations. The businesses have bought hundreds of exoskeletons to rehab clinics and private customers, they usually see room for development; in america alone, about 300,000 folks dwell with spinal wire accidents, and hundreds of thousands extra have mobility impairments from stroke, a number of sclerosis, or different situations. The VA started supplying gadgets to eligible veterans in 2015, and Medicare not too long ago established a system for reimbursement, a transfer that personal insurers are starting to comply with. What was as soon as experimental is slowly turning into established.
Researchers who take a look at the gadgets say the know-how nonetheless has vital limits. Pal, of the New Jersey Institute of Know-how, mentions battery life, dexterity, and reliability as ongoing challenges. However, he says with amusing, “Our our bodies have developed over many hundreds of thousands of years—these machines will want a bit extra time.” Pal hopes the businesses will preserve pushing the technological frontier. “My lifetime objective is to see the day when somebody like Robert Woo can get up within the morning, put this machine on, after which dwell an atypical life.”
For Woo, the actual query concerning the self-balancing Wandercraft was: May he prepare dinner with it? Within the VA hospital’s residence mockup, he tried it out within the kitchen, stepping sideways to retrieve objects from cupboards and squatting to seize one thing from the fridge’s decrease shelf. For the primary time in years, he may work at a counter with out leaning on crutches. “The self-standing exoskeleton adjustments every little thing,” he says. He imagines a consumer putting a Thanksgiving turkey on a tray hooked up to the swimsuit and strolling it into the eating room.
Again within the showroom, Woo finishes the demo and brings the swimsuit to a seated place earlier than transferring again to his wheelchair. After so a few years of testing prototypes, he’s now practical concerning the know-how’s timeline. A very all-day exoskeleton—the sort you reside in, the sort that replaces a wheelchair—could also be a decade or extra away. “It might not be for me,” he says. However that’s now not the purpose. He’s fascinated about younger people who find themselves newly injured, who’re mendacity in hospital beds and attempting to think about how their lives can proceed. “It will give them hope.”
