Skin cancer seems to be very much correlated with overdoing it - i.e. severe burning.

Sun will definitely age your skin, but for myself, I'm now trying to be out in the sun as much as reasonably possible, without lying down and "sunbathing". Just keeping active. Avoiding the hottest hours (like they do in Southern Europe). Go inside when/before it starts to sting. It feels good and it feels healthy. It works on several hormones, but even forgetting all that: it just feels good. Even Albert Camus was convinced that sun is extremely important.

Sure, it depends on the climate, and some people really have to protect themselves, there's not one golden rule. On the other hand, the "protection" factor on sun oils is calculated on a very thick covering - most people don't even use 20% of the intended/tested layer, as the correct covering will turn you into an oily blob. (and cost a small fortune)

I suppose it's one of these risks that we have to calculate for ourselves. Maybe avoiding sun and constantly using oils may be worse for your health in the long run. Or you may live longer but unhappier?

Just thinking out loud, and hope I don't have to eat my words.
