THE AWESOME POWER OF THE SUN — and of modern technology: We’re on vacation, and yesterday we went sea kayaking. (Thanks to “scheduled posting” the blog perked on!) The sun here in South Florida is pretty strong, and I slathered up with 30-power sunscreen. I wasn’t the least bit burned even after a full day, except for one small spot on my foot, which somehow got missed when I slathered the sunscreen on. Downside — it’s nasty. Upside — boy, it sure proves how well the sunscreen works. Sunscreen makes such a difference with what you can do outdoors in the summer; it’s one of those humdrum inventions that has a lot more impact than you tend to think. Er, when you actually get it onto your skin. . . .
