Steven D. Levitt at Freakonomics asks (and answers) the ever-annoying question: why get a tattoo? After rejecting the obvious, he zeroes in on the one reason we get inked (and do everything else): Sex.
Levitt admits that he has never really wanted a tattoo, partially because they are so permanent. "Economists tend to like choices that are reversible," he muses. "Whatever my preferences might be today, who knows what they will be a week, a year, or a decade later?" For the risk-averse among us, tattoos can certainly seem like a huge gamble. They are not for the wishy-washy or those plagued with regret (for her sake, I hope the Twitter fan from this morning does not fall into this category).
