re: "Thanks for the explanation . Your post was quite witty, but I'm a little slow on the uptake sometimes!"
As I approach 78 y.o., and with so much lost, i'm glad I still have my biking legs and (according to some) my wit. I still hear startled gasps from some I have just met when they hear my age. I will occasionally say to them "Well, I'm just visiting here. On my home planet, we live an average of 200 earth-years. I'm just approaching middle age." Someone asked me yesterday how many believe that line. I told her that I couldn't remember - the memory is the first to go.
