Our happy hour fact to amaze your drinking buddies with.

18-to-29-year-olds (aka "millennials" or "Generation Y") lead the nation in getting tattoos.

According to a survey by the Pew Research Center, 38 percent of "millennials" have at least one tattoo. While that isn't a huge increase over the 32 percent of 30-to-46-year-olds who have body art -- only about 10 percent of those over 46 have a tat -- what differentiates the younger generation is how many tattoos they get.

50 percent of all inked millennials have more than one tattoo, and 18 percent have more than five. Among 30-to-46-year-olds with a tattoo, half only sport one; only 9 percent have more than five.

Given that millennials still have many more years of questionable decisions in front of them, for some 18-to-29-year-olds, it could be a case of their amount of bare skin being the limit.
