I'm 53 and I have been riding for 40 years of those with a 7 years period of not riding. I used to commute from the start and done so in snow, wind and rain. Taken my bike on deployments around the world and done touring, execersise and commuting around the base.
Almost a year and a half ago, I started to commute again, after 7 years of not riding. I was 45lb over weight (I'm 5'8"), slow and commuting in South Florida (read "no regard for cyclist) when I started to commute again!
Well, after a year and a half of riding 14 days out of the month to work, 25 mile round trip with a train ride in the middle, I have renew my excitement for commuting. Lost 35 out of the 45, feel better than I have in such a long time and loving every minute of it.
My bike is my gym, my heart doctor, therapist, friend and wheels! It is a great thing!
