I saw a guy recently say he was 44 and seemed to be telling the truth. flufluflu I think was his name. Not sure though, could have been bait.
I remember hearing a few years ago that Jon E. was 40, so yes, I think he's older. CS has a lot of old fans because it's been around for 20 years and for some reason this stupid game stays with you. I don't even play and haven't for years, but I like to keep up with it. It's weird, no other game is this way for me.
