Yeah, that sunscreen stuff?
Also, when you're out on your parents' pontoon boat.... make sure the SPF is high enough.
Here's a hint: if you're as pale as I am, SPF 15 is NOT high enough. Even if it does protect from both kinds of UV rays.
I look like a cooked lobster. My knees got the worst of it so I've been waddling around the house all day - thankfully I have at least a little bit of silk clothing, though not much - only thing I can wear without feeling like somebody's trying to sandpaper my skin off.
