I can definitely relate to this sentiment. I started working in an office environment at 18, and have been moving up in position exponentially since then. At 22 I'm now in a position where I'm senior (in that I am a developer, and the people "below" me are junior developers) to a few developers. The first 2 companies I worked at were large enterprises (50k+ employees) where i'm sure I was either one of or the youngest working there. Age become a particularly complex issue when I was 19, and working in a lab. Often I would experience age harassment from a QA lead (who was later fired...) Things got a lot easier after I turned 21 though. Still I find it easier to get work done If I ignore the subject of age as much as possible... unless one of my coworkers has discovered my HN username, I do not believe anyone other than HR knows my age at my current company.
