I'm a 26-year-old writer who recently got back from living in Japan. I used to be a very active person in my teens - dance, rowing, fencing, horseback riding - but my health has been a roller-coaster ride over the past six or so years. I want to get in even better shape than I was in high school, and above all, be healthy and happy.
