HAHAHAHAHA. It's funny 'cause it's true! Having somehow acquired the plague on my vacation (which later turned out to be an upper-respiratory infection), there weren't a lot of very physical activities to which I availed myself. I was perfectly content reading in pretty much every location at the resort. And the portability of my book collection is only aided by my recent acquisition of a Kindle. So it was not uncommon to find me nearby to various bodies of water with Kindle in hand and a far-away look in my eye, and a glass of orange juice someplace close.
My best guess is that if you're going to be miserably sick anywhere, it's best to do it someplace tropical where it's not impeding your work or anything. On the other hand, who wants to be sick on vacation?
