I just read this and watched the video (without sound because I managed to mess up my audio card &^%*) but it reminded me of a conversation I just had with my son about aging and knowing that you're aging.
Would you know when to hand over the car keys? When to stop kicking ball? When to stop drag racing? When to stop wearing muscle shirts or mini skirts? (hopefully not a combined problem for you now).
Would you know when do you say when? Or would you cling to it all...?
