I'm not saying he burnt his nose in the sense of a sunburn but more like irreversible sunspots.
Yeah, I trust the science since I'm a pharmacist, so I guess you could say I'm a scientist too?
for the connection between health and nature I still don't really get it m, but if you've got studies to back this up feel free to share.
Honestly I'm not really sure where you're going with this. Are humans supposed to spend hours in the sun just because their ancestors did? Prehistoric humans had to spend hours in the sun out of necessity; I'm pretty sure if you offered them a roof, a couch, and an air conditioner they wouldn't say no. I get that some people love the sun but there are people who love cigarettes too and that doesn't make them any less harmful.
If you want to believe in some unfounded theory that you can train your skin to adapt to the sun  nobody's stopping you. But the facts are there: the sun damages the skin.
