"I&amp;#x27;ve noticed something a little perplexing lately: I always seem to be driving south when the sun is rising, and north when it&amp;#x27;s starting to set. Because I&amp;#x27;m the driver of the car, that means that my left side is constantly bathed in sunlight--and my left arm seems to sport more freckles because of it (even though I apply sunscreen religiously). So this case study was shocking--talk about proof positive that sunlight affects your skin. Dr. Jennifer Gordon, a dermatologist from UT Southwestern, submitted a fascinating case study to the New England Journal of Medicine about Bill McElligott, a 66-year-old who has been driving a truck for the last 30 years. After delivering milk to stores around Chicago almost every day from 6 A.M. to 3 P.M., McElligott now looks like he&amp;#x27;s two different ages. The right side of his face, which mostly stayed out of the sun, is 66. But the left side of his face, which was constantly touched by the sun, is 86. You must take a look at his startling photo here. McElligott has unilateral dermatoheliosis, caused by repeated, long-term exposure to UVA rays of the sun (which Gordon says can easily go through a car&amp;#x27;s glass and cause the most damage): &amp;amp;#8220;It (UVA) can penetrate more deeply into the skin than UVB and affect your collagen and elasticity. When you destroy those that&amp;amp;#8217;s what gives you the aging appearance that we see,&amp;quot; she says. And according to another dermatologist, lots of people have more sun damage on one side of their body: &amp;quot;Most people are completely unaware and most people who come in to have sun damage treated, they often times will point to their left side saying they see more spots, more wrinkles, more aging, but never put two and two together,&amp;quot; says Dr. Mitchell Chasin, the medical director of Reflections Center for Skin and Body. Sunblock! Sunblock! Sunblock! Every day. McElligott&amp;#x27;s case serves as an important reminder for that--even for himself. He says he wears it every day now, and carries it with him just in case. He also plans on having the older side of his face treated so that it looks like the younger side, saying: &amp;quot;That way my grandkids will quit asking me, &amp;#x27;what are these bumps, grandpa?&amp;#x27;&amp;quot; Startling, right? Do you notice a change from your left side to your right?
