It's interesting that she did not change her routine to fitness exercise until she was in her 60's, “In those days I was more than just a little plump—my trouser size was twice what it is now. And yet, I stubbornly refused to admit that I was overweight. One day, however, my husband made a comment about my weight, and that was when I decided to join a gym.”
This is an encouraging way to stay young. Takishima Mika says “age is just a number.” She's a 90-year-old fitness instructor.
Personally I know once you start working out constantly then see and feel results it becomes addictive, “I only got into fitness because I wanted to lose weight. Once I had done that, however, I decided I wanted to have a nice tight bottom like a Brazilian woman. Then, once I had achieved that, I decided I wanted broad shoulders and a narrow waist. The next thing I knew, I was teaching aerobics classes. I never dreamed my life would play out like this.” More here.
