thank you for the link. i will go check it out. is it true you have to post **before going into chat. i want to talk to folks who have had this done. i've had surgeries to my knees/shoulders, and even c-sections and surgery for uterine cancer... but, this seems so invasive and to be under anesthesia for so long... just worries me. i'm not so young anymore and the risks are high. my children, although older, are unable to drive. that is the biggest challenge... getting them to and from school. thanks.
