In that insane period in your life just out of high school,  climbing trees was a beer thirty activity.  Find a couple of like sized 20 year old firs,  and race each other to see who could break the top out and make it to the ground first.  I thought I could let go,  and grab a limb to slow my descent.  Wrong.  I caught the limb, one handed.  It swung me into the tree and quickly broke and my butt limbed one side of that tree before I could grab a second limb.  Bruised and bleeding butt,  skin missing from hands,  and the top in my teeth,  I won!!   Had another beer.    A day later was aghast at the wounds to my back and legs and arms.  Beerstupid.
