Your as young as you feel bro! If your still climbing at 46,you certainly cant be crumbling too bad. What is your secret to to still be able to go at it? Absolutley not fast cars and fast women I hope.My uncle always said that the only way they would get his saw was to pry it out of his cold dead fingers. You are indeed am inspiration for all of us young whipper snappers. May you live for many many more years to come. I bet you have got some great stories about the good ol days before brush chippers. Now thats when men were men!
