I always felt very lucky that I didn’t inherit my mother’s propensity to sunburn. I wore sunscreen constantly as a child because I was afraid I’d turn crispy from mere moments in the sun. To this day, I always wear sunscreen on...

Birds move. Actually, they do better than that: most birds fly. And the distances these tiny creatures can cover is jaw-dropping. On top of that, can you imagine the views from a bird's vantage point as it flies from South America to Canada?...
