This is the most important reason I work out. I want to be able to do this shit when I'm old, and also be able to keep up with my children, grandchildren and maybe even my great grandchildren, I want to be able to lift them up on my shoulders, I want to be able to keep up with them running around and not just want to stick em in front of a TV or PC and hope they don't want to do stuff that'll make me sweat. Of course I want to play some video games as well
