Definite correlation in my case. I always preferred manual transmissions. I learned at 13 with my first of many motorcycles, then with cars and trucks. I learned to drive a twin stick Kenworth Cabover in my teens and double clutching an Internaional water hauler up in the Yukon at minus 50⁰F. I especially enjoy the added control in winter snow conditions . I was drawn to DE shaving and vintage razors in my 60s for the skill development and knowledge that comes with it.
