Thanks for your concern. But I am not sure where you got the idea that I said I was unhealthy. I just assumed that I can skip gym and get all the health benefits of it by taking 10K steps.<p>But yes as a geek I love data, and I really enjoy charts and numbers. And yes if I go to gym and find out I left my heart rate strap at home, then I might feel discouraged and not workout as hard. Perhaps I will make a habit of working out without HRM once a week.<p>As I tell my friends, only health device you really need is yourself.
