If you have a few hours to kill, check out this interactive F1 timeline that goes through every driver who's ever participated in the sport. Hover over a spot to see race details, and be sure to check out how old (relatively speaking) the drivers were in the early days.
Yeah, the age thing is super weird. I watched Weekend of a Champion recently and watching Graham Hill talk to Jackie Stewart was weird. I actually wasn't even fully aware that they raced together until I saw that. I mean the mustache alone.... misleading.
