Wrinkles are a new place to store illicit stimulative materials. :^D
Seriously: there's something about people born in the second half of the 20th century -- this general refusal to ever fully grow up.
My folks were born way way back in the first half of the 20th century; and it often seemed to me like they had been forced by the times (depression and wars) to grow up too fast. So our generation is subconsciously trying to counterbalance that by going the opposite direction.
I kinda wish I knew how to strike a balance between mature and dynamic; but I don't. So like many of our generation, I'll be buried a geriatric child.
Hey, there's a name for a bar band: Gerry and the Atrics.
