It was a belated 40th birthday present to myself and also a belated reward for giving blood 50 times, since you have to take a few months off donating after a tattoo.
I'd hesitated because I have many interests and I'd never been sure what I wanted most. In the end, I went for the OO7 logo in current use on the James Bond novels (because I'm too much of a literary snob to go for one from the films), on my left wrist where it would usually be concealed under my watch.
It seemed to take ages, and it was mildly uncomfortable at best (at worst it actually hurt), so I admire anyone who has sat through a large and complicated design, but I am pleased with the results.
I wrote an accompanying article about Bond and tattoos for the Artistic Licence Renewed website:
