I just saw your post and would be happy to help in a study but I don't live in your area,I live in Texas. If I can still be of help then please feel free to contact me. I will be away from a computer for about a week and a half, going in for an Aorta Bi-Femoral Bypass surgery on the 4th of Dec at the V.A. Hosp. in Houston Texas.
