Unrelated: I used to go to tech meetups in my city fairly often. There was one guy who always seemed to be there just for the food. I only knew him by his username ('Lex R' - a programming pun) and never talked to him. Tall skinny dude; if I had to guess, I'd say he was around 50ish.

Every meetup without fail, this guy ate so much pizza. One time I counted 11 slices. He also drank at least a 2L of soda - didn't matter if it was diet or regular, he drank it. About 10 minutes before the meetup ended, he'd put a bunch of leftover slices in a pizza box to take with him. And he had a bottle of some kind in his bag that he'd pour the dregs of all the soda bottles into, and would take that with him too. It was weird because it was a tech meetup, presumably most people were making at least 6 figures.

Until today I had never considered that this might be his only source of food.
