I like to stay fit and healthy, but I'm constantly fighting my lazy-bug and sweet tooth in this regard. I do manage to get an hour of weekly exercise in though, of which I'm, disproportionately, proud.
I write for a living and it is also a hobby. Professionally I've written on mental health, health and fitness, music, film, aviation, food and money. As a general rule I write on my passions, but many things interest me. So I intend for my professional writing range to grow accordingly.
