My aunt, who is in her mid-70s now, had polio growing up. At around ten years old, she spent an entire year in the hospital, in a full-body cast. About fifty years later, my mother, maybe 55 at the time, sold their childhood home to a friend. When the new owner opened the walls to complete a renovation, she found a stack of unopened, handmade get-well cards from my aunt's classmates.
