I commute 4 miles each way for a total of eight miles. I usually ride old bikes from the '60's, which are heavy, so it is like doing more miles in terms of effort.

Usually, I do all my other travels and errands by bicycle too, which all adds up.

I commute all year, even in winter when it is -10F to -20F and when it is snowing and rainging. Yup, I have a working automobile, but it sits for weeks at a time without being used.

A day without bicycling is like a day without..., Hmm... well like a day without, Uhm, well a day without bicycling sucks.
