Here's an interesting little article about gamer competitiveness fading with age...

At 44, I can say (from my perspective) that it's pretty accurate. 20 years ago, I was all about the frags, the PvP, the teabagging, the hardcore modes (permadeath), the twitch combat, the bragging rights etc.
Over the years though, this has changed and now I'm quite happy to just take my time exploring and helping others in PvE dungeons over a glass or two of wine. PvP just doesn't interest me at all any more. It's just too stressful and I know I'll never again match the abilities of an 18 year old hopped up on energy drinks and youth.
Anyone else getting old with me?
