Ok, I'm getting the idea that a few hours is bad. I'm 62 and I have been a server (waitress) for 40+ years and I am still working with, and if not keeping up with, passing 20 and 30 year olds. I forget that, while nothing else around me has changed, stuff *inside* me has. You'll all be glad to know that instead of quilting, I went out and worked in the garden for uh, 7 hours. At least I used different muscles!! Honestly, though, I'm getting ready for them to sell the urban farm in a year, so I have to turn it back into a plain old duplex again. So, there's a lot of "we might need this some day" to get rid of.
