There are so many things as adults that we have to worry about, that sometimes it seems like it might be better to be a carefree, young child again.
For instance, playing outside is so much better when you're not concerned about...
*the fact that the dirt you are getting ready to play in is actually full of dog or cat poop
*remembering to protect yourself from harmful UV rays
*that the friendly "spider" you're about to touch is actually your friendly neighborhood stinging wasp/bee/hornet
*the cars that go flying by on that "road" you're trying soooo hard to get to
*trying new outdoor cuisine aka rocks/grass/dirt/bugs/pet hair
Never mind, I think I'll keep all of those things I need to worry about if it means I also get to keep the wisdom that comes along with age ;)
