Since last summer, I've noticed I can never sun burn. And in fact, it is hard for to even get a tan (and I tan beautifully).
To answer the next obvious question, no, I never wear a shirt as my physique is that of a Greek god. Well like David. Just with one big difference.
OK. I'll just say it. Chem trails blocking the sun's ray to deny us the natural protection of vitamin D. Bill Gates said he wanted to block the sun, didn't he? Well the healing part of the sun for sure.
Sunny and clear skies where I am I've had no problem tanning, in fact it was too hot this summer. Now it's beautiful 70d during the day dipping into the 40s at night.
