It's good exercise which makes you healthier, rather than sitting on your butt letting a machine do all the work which creates pollution making our planet unhealthier. It requires you to be in the present moment forcing you to deal with yourself in order for you to produce the physical energy it requires to move forward rather than expelling mental energy thinking in circles always impatiently hurrying chasing the moment that you never quite catch. No wars were fought and no people died for the fuel it takes to pedal it. I miss my truck and it's been a real hassle not having a vehicle, but life isn't a race unless, of course, you're running from the truth and a little hard work.
