When you take a look at this photo you will NEVER want to go out into the sun again . . . without a sunscreen that's an SPF 45,000.

The photo is of a 69-year-old man who drove a delivery truck for 28 years.  (--His name wasn't released.)  So for 28 years, the sun was on the left side of his face for several hours a day, every day.

And looking at his photo now, the right side of his face looks normal for someone in their late 60s.  But the LEFT side of his face . . . which took all those decades of sun . . .  looks like the face of someone who's at least 100 years old.

We all know too much sun makes your skin look old . . . but seeing the effect on one-half of one person's face is SHOCKING.

Two dermatologists at Northwestern University just published a report on the man as part of their study on just how damaging the sun can be to the skin.  Their verdict is . . . it might even be more damaging than we believe.
