Younger Guys

I have been thinking about going younger for a few months now.  I think I should do it!  I like that younger guys are more playful and don't really have wrinkles/deep creases.  Goodfella thinks I should go younger because guys in their late 30s are usually set in their ways and very resistant to change.  Totally superficial, but what about those years of sun damage causing serious wrinkles?
