I felt guilty when I bought my new bicycle. I had recently retired and had only recently returned to cycling... with hopes it might reverse my health issues. My lovely wife did not support my purchase. Which made me wonder if I was making a good decision. But I knew I needed a better bicycle to get up the hills that had me pinned into my own neighborhood.
That was in 2010... and the bicycle turned out to be one of the best buys I've ever made. I lost a bunch of weight... my health is now excellent. I ride a solid 2000 miles a year (in the seasonal Midwest). And more than that... the bicycle has provided me with a vocation of sorts in my retirement years. I've got a lot of happiness for of the price of a bicycle. A bargain!
