What does the old professor do in the summer?

In the summer, I spend a lot of time preparing for my fall courses -- a lot more time than any of my students do, I'm sure. There are so many new developments in marketing that it takes a lot of research to keep up (whereas I don't think Shakespeare has written anything new lately that Literature profs have to bone up on!). And there's the continual flow of new editions of texts, or wholly new texts, that I have to at least skim over. So think of me while you're lying on the beach and I'm in my study at home doing what? Studying.
