Tattoos have been around for more than 5,000 years. Egyptians, for example, used tattoos to differentiate between peasants and slaves, a kind of social branding. But ink art, which is what some fans like to call tattooing, has really exploded in the past 25 years. But not all of us have succumbed to this fad. And many of us who don’t have a tattoo have a favorite mug. Having a tattoo or becoming attached to a mug are not dissimilar. According to research, 60% of Americans say they have an emotional attachment to a favorite mug. And about 40% said their special mug was irreplaceable, and about 1/3 of those said they would be devastated if it broke. Personally, I think that most of these people don’t have tattoos. Mugs and tattoos are both an extension of our personalities, and both express the way we would like the world to perceive us. That is not to mention, of course, that those of us who have tattoos or mugs are often irrationally attached to them.
