There's a GI doctor who is in his 80s who still works but should have retired years ago because he's lonely and will drag out cases if he has nowhere else to be. He won't retire because he said his father died right after he retired. He broke his hip 6 months ago and we figured that would have been the beginning of the end and he'd never come back. Not only did he come back, but he is faster than he used to be, albeit it marginally.
