re: What’s the youngest age that a friend of yours retired?

one of my college roommates came from nothing and retired in his early 30s. Started at space-x out of school when most people hadn't heard of them. Sign on bonus was in (at the time) worthless stock. There's apparently a video of him rappelling off of a rocket (or significant piece of one) that is now used in a "don't do this shite anymore" video.
