Pro golfers look a good 10-20 years older than their real age sometimes fwiw. In contrast to most other pro athletes in indoor disciplines who generally look better than their age. There's also examples of truckers who spent most of their career with the window rolled down and you can tell straight up what side of the road they drove on.

Truckers, plural? Is there an example that isn’t William McElligott from the famous photo[1]?

Edit: self answer, yes[2] (left side!)

I first took sun exposure seriously after backpacking and spending time with other young travellers in hostels. It was apparent who spent their time exposed to the sun, I remember a girl my age who was in the middle of a multi-year cycle tour, and although I envied her journey, her skin looked quite rough. I decided that if I ended up doing that, I'd get one of those cycle helmet brim visors and would probably just cover my face during a lot of the riding portions.

Then I met a man who did kayak tours of a city. He was awesome, but really leathery due to the 20 years in a boat without shade and having the UV reflections off the water. Your skin cancer risk is off the charts at that point.

The sunny side of the road?

Those drivers don't even need to have the window rolled down as far as I know. That's because most door auto glass lets UVA rays through and that's what causes premature aging. If you want to block those UVA rays, you would need to apply some kind of additional film to the side window.
