Yeah, I definitely noticed a big drop off on my reaction times in my mid-30s which makes it a lot harder to trust yourself not to get hurt... and the injuries take so much longer to heal.

It's such a different world now... we weren't allowed inside until dinner time. I have no idea how many hours I spent just doing stupid things in our backyard... but I guess the other side of that is I probably wasn't learning at the same incredible rate as kids with an iPad now.
