What's your Tattoo Personality? You can't turn on a television, open a magazine or spend thirty seconds online without spotting another celebrity tattoo these days. From the silver screen to extreme sports, from the catwalks to the hardwood courts, bikers and babes, hotties and hunks -- they all sport ink. One in three people aged 18 to 35 has at least one tattoo, and two out of every three people has thought about going under the needle of a tattoo machine.
