It does amaze me how some people choose to drive short distances, but will then spend extra time (and money) driving to the gym to stay fit. I commute six miles each way, but some people drive half that distance yet moan about their lack of fitness and claim they don't have the time to fit exercise into their day.
Don't get too many of the 'you're crazy' comments any more, though had one or two raised eyebrows when I showed up on time for work every day last week when some of those living closer and coming on the same route couldn't drive in because of the snow (hmm!)
