When I was 11 I think I had my tonsils out. But can’t remember much else about it. If any medical records from that time period still exist I’d be amazed. Seven years for old tax forms, old business records, nobody keeps that clutter around forever. I mean nobody except hoarders keeps that junk around. I went to an estate auction recently where the guy had so much paperwork they auctioned it off by the roomful like a storage locker.
