Students, stay out of Starbucks!

Just for fun and edification, here's an interesting little economics lesson on the opportunity cost of drinking too much Starbucks coffee during college or grad school. It would also apply, of course, to ordering take-out pizza or Chinese instead of eating dinner in the dining hall. I was going to say that it applies to beer, too, but I guess the calculator in the article wouldn't work right, since making your own beer at home probably isn't an option.
