I was just watching Titanic and spent 20 minutes looking up the effects of hypothermia and discovering that Jack may have been alive and in stage 3 hypothermia when Rose let go, and because he sank instead of floated, he was in fact alive. It was a fun little time sink. What rabbit holes have you done down recently?
Also Titanic. Spent a lot more then 20 mins myself though. I’m on like week 3 of my Titanic rabbit hole
