The incredible stress and difficulty I had in solving the problem of how to run with keys, led me to pursue a keyfree lifestyle.
I started with a pilgramage to Nepal to learn the secrets of spiritual happiness. I continued with over 30 years of the study of Zen.
I sold my 6 bedroom house, left my wife, quit my job and gave all my money to the destitute.
I now own only one pair of running shoes and a pair of running shorts and there are no locked doors in my life. It has been a long road but at least I never have to worry about where to put my keys on a run ever again.
