If staying under the sun gives you “skin cancer”, then why there are so many “rednecks” who reach 60+ years old?

Rednecks stay under the sun A LOT. That’s why they are called like that (they get red necks, because of staying under the sun many hours). And I don’t think they put any sunscreen, because it’s too “metrosexual” for them. So why people criticize, if you stay under the sun, even with sunscreen on?
