Another thing is being a captain and driving a car in the US my left arm was usually exposed to the suns rays. Now at 67 my left arm looks like it is 90 years old and my right looks 60. My left arm bruises with the slightest bump. Something to think about, I didn't. I could feel the warmth in the cockpit on my left arm but did nothing to protect it from the sun. Once in a while my FO would give me a sunshield but I did nothing myself. Sun damage to your skin takes a long time but it will get you as you age.
