David Stearns, a loyal MR reader, asks:
How would you pick a tattoo, if you decided you were going to get one? How would you pick something that your future self is most likely to be glad to have? A favorite piece of art? Follow Leeson's lead and get an economics-related tattoo? Names of family members are off-limits, as are answers like "get a small dot in my armpit that nobody would see."
I would pick a country which I loved visiting, such as Mexico or Brazil, both of which have distinct shapes. It would be an excuse to narrate previous visits and I don't think it would repulse many people, other than the fact that it is a tattoo. An artwork in tattoo form would look low-brow. A Celtic geometric design would be another option. The obvious alternative would be to pick something which looked criminal, but I don't think that would mesh well with my other strategies in life. For some men it would pay off.
Here is Dan Ariely on tattoos.
