OK youngster, the arthritis can be helped with exercise, nothing heavy, just stretching excercises while sitting at your embroidery machine can help (I do it all the time) - takes some of the guilt out of sitting at the machines for hours on end.
As for the frequent "potty breaks", I laughingly refer you to the recent commercial that Whoopie Goldbert did for "Poise", adult panty liners. I'm tempted to go out and buy some, just 'cause I love the commercial. According to Whoopie, Cleopatra, Lady Liberty, and several other historical women suffer from occasional "dripping" and would have benefitted from this product. If you haven't seen the commercial, look for it and consider the product for your "problem"
