Hey I just found this web site! I'm so gals to see I'm not the only grandmother! I haven't started anything yet, just in the "talking" stage, but the more I read from the complications the more nervous I am. My husband is not for this at all. I am needing knee surgery AND back surgery hence my last option as they are telling me. I'm trying not to back out, I'm just scared, sonim very glad I found this site
