Tattoos: The good, the bad and the bumpy

The body art might appear cool, but it can pose risks. Some people react badly to the inks-substances that aren’t meant to go on or in the body. Other people may have trouble getting certain medical tests after a tattoo. And not everyone is as thoughtful when they are selecting their design. Many people get inked on a whim, and later want that permanent art removed. It can be done, but it’s a long and painful process.

Still, research now indicates tattoos aren’t bad for everyone. In people who heal well, getting a tattoo may prime their germ-fighting immune systems for action,and in a good way. The rub: Until someone gets a tattoo, there’s no way to know if they will be someone who benefits or instead be harmed.
