At some point in my life I had to claim to be born a lot earlier than I really was. Steam used to think I'm in my 80s. Now that I really am old enough to look at whatever content I want, I usually end up selecting some year much younger than myself, like 2002.
Every online form thing that asks for an age I pick the oldest age possible so on some sites I'm part of the 100 year old Kissinger club.
