GAS (Gear Acquisition Syndrome)
is really hard to fight sometimes. I try, but not always succeed in controlling my urges. If I didn't, I'd have about 25 helmets and 25 jackets! That's my addiction. I control it and only have 3 helmets and 3 jackets.

I mean, I like adding stuff to my bike, but I often find myself going to specialty sites talking about the new helmets and new gear coming out. It's hard not to get involved in the spirit of acute upgraditis!
My other GAS is for my drum kit, which keeps growing every year... to the exasperation of my wife!
Oh, also adding Apple stuff around the house... easier with Steve Jobs gone... he could really make me feel like I NEEDED to have his new gizmo! (Although the new and upcoming Mac Pro makes me drool a bit, fortunately, I do not need that kind of power now, so I should be fine... my wife too!)
