sumac, thanks much for that link. I've filed it among my favorites so I can research at leisure.
Danon, I'm in pretty good shape for the shape I'm in.
Stradee, bungee jumping is one pastime that holds no interest for me whatever. If uou're gonna do it, do it right, I say.
Piffka, I tried ballroom dancing in my younger days. Unfortunately my sense of rhythm is such that every waltz turns into a tango (or is that 'tangle'?). I'm so glad all the new dances, where you don't even touch your partner, are so free-style that one can do anything one wants on the dance floor and nobody will point fingers or laugh at you!
