I just went to a wedding, and my (fat) cousins were all teasing me because I'm so white, saying I should get out in the sun.  They were all nice and brown from the sun and the tanning salon. I spend hours outside, especially now in the summer.  I've done multiple century (100-mile) cycling rides, plus a couple of triathlons.  I just use a TON of sunscreen (zinc oxide 4 life), leave at like 4:00 a.m. if it's a really long ride, and wear long shirts and pants.    Sorry I don't want skin cancer, you mouth breathers!
