Surfing would be good. I do like this woman's reasons for dropping some pounds. I was a little shocked to read about someone wanting to reduce the burden on the healthcare system as part of their reasoning.
BTW, I doubt that you need to reduce your size in a any way, shape, or form.
I am doing it for the same reasons (now). It's all about health and vitality and looking good. No matter what I do I will never look like Britney Spears and a girl shouldn't lose weight for attention from guys anyway. I think her motivation is awesome because I think healthier citizens make for a healthy country.
