When Matthew Sanders was a patient at the University of Chicago Medicine Comer Children’s Hospital, the staff regularly encouraged the teen to take a break in the playroom on the first floor. Time and again, the 17-year-old said no. He didn’t want to be in the hospital, much less hang out in a place for little kids. When he finally relented, Sanders discovered the teen area—and its pool table. From that point on, the playroom provided a respite from his treatments for bone cancer.
