I have a theory on why kids do some wild things that us older people won't, their brain isn't pain trained yet. In the past I learned that you should always venture into risky situations using the limb less useful to you. For example a right-handed person usually uses their left hand for risky situations. That theory worked great for me until I had my arm broke at a karate tournament, now I use my right arm to test the water.
Someone also mentioned if toughness is an inherited quality or a fact of just having to work hard. I believe both to be true, but I favor the strong mental attitude. Our son used to work with us on occassion, and he could go like crazy until about noon, then his Mom could out perform him. I always wondered if we as society as a whole were getting softer, According to my Dad I wouldn't have kept up with him in his day, and what I remember from my Grandad, at 65, he could outwork all of us put together.
