60!
Right now my success is mostly due to portion sizing, drinking water more, and cutting back on junk food. In two months I hope to be down another 15lbs. Winter will be over (54 days til spring!) and I will be walking a lot more. I live really close to the mall now so I'm getting a February bus pass and will be walking in the mall with all the old folks before the stores open.
Our mall is particularly awesome for this type of walking workout because it is just a long corridor of stores. Everyone walks up the right side just like on the road. It's pretty long too so two or three times around and you've been walking twenty minutes.
It's pretty amazing seeing all the groups of elderly people in track suits with water bottles (some even have small weights) in hand speed walking passed talbots and HMV. You know these people are going to live independently a lot longer than some of their peers, simply because they are moving more. The more you weigh later in life the harder it is to care for yourself and it can lead to accidents and illness. So no matter what your age, exercise is a vital part to a healthy lifestyle. In fact exercising daily prevents more heart related illness and cancers than proper diet alone. Something to think about.
Oh I feel like a public service announcement. >.<
