Wear That Sunscreen!

I can’t tell you how many times I was outside blissfully enjoying the sun during my travels, and then got badly sunburned, ruining the rest of my week. Wear sunscreen every day, even if its cloudy out, or you’ll regret it later because you can’t sleep — or worse, end up with skin cancer or other problems.
Especially when you’re traveling to places near the equator, or at high altitudes, wearing sunscreen is key. And remember to pack your own, because it can be very difficult to find in some countries where it’s not widely used.
