Thanks again guys!
Bob - We're still working hard on making this displaced Canadian a permanent proud US citizen. ;)
As for the rest, other than the notoriously bad joints which obviously haven't started improving with age, I can't complain because I'm in the best shape of my life, having traded my rock and roll habits for more healthy ones.
I guess not until I turn 80 will I feel as old as I did in my late 20s. :P
