Cycling helps clear my head of all the crap going through it at a million mph and then I am able to focus on what it important. I have actually solved problems in the workplace coming up with solutions while I am out on a ride. If I am grumpy around the house, my wife tells me to go foa ride and I come back all happy. Cycling does wonders for the mind and body (and hopefully is a life extender in the later years).
