Well, I am almost 40 as well. The first F1 season I watched on TV was way back in 1972. I actually have a fine model of Emmo's (JPS) Lotus 72D on my shelf now. My first racing game was "Accolade Grand Prix Circuit) in 1998.
It seems that many of GP fans, especially the creators of add ons, are a bit older than most would think.
I guess if one is a racer he will always be a racer
(as I tend to say) Keep on racing: Bruno
