Thanks, Kgem. I don't expect any problems but after a nuclear stress test my doctor thought I should have one. Have been a life-long jogger,golfer, fisherman, river-floater, etc, but after 3 back operations, I'm now a computer nerd. Guess I'll have to find a non back aching exercise. Don't think this board will miss a beat with me gone. I'm just a good cheerleader here. But I do own a few shares!!!
