Real-world Healthy Eating and Cooking in Food Traditions & Culture Posted July 24, 2005 Ducky, I have a friend who had to have both knees replaced. They refused to do the surgery until she lost weight. She started a strict diet, but diet wasn't enough. They told her to sign up for water exercise at the Y. Like you, she was mortified at the thought of people seeing her in a bathing suit (She's also about 30 years older than you.). So, the first time she went, she wore sweats. After she saw what everyone else looked like, she immediately went out and bought a bathing suit. If nothing else, why not just go and look in on a class before you sign up? I wish you lived closer--we'd go together! And BTW, my friend lost her weight, had her surgery and is doing great!
