I wasn't always a fitness freak, and usually during the winter I'm building up some chunky reserves like if I was going to have to survive for weeks with just water.

So my first mission to "get back in shape" when I hit the big three O, was to stop taking the subway, and bike 6km to work and 6km back every day. For more than 5 years, I hadn't even considered riding my bike to work, as that was too demanding.
