How are you doing since surgery? Just followwhat the doctor tells you. Don't rush things. You will do great. Who is Dr. V with? What are nutritional exercise classes. I haven't had any of those. I really need to be exercising but have not done so yet. I have a bad knee so limits me a great deal. I hope to get into a water aerobics class. Good Luck and if I can help you, please don't hesitate to get in touch with me. This is my work e-mail address. My home e-mail is marthahjo5@alltel.net.
