Tattoos — The Upsides and Downsides
CON: Permanence

For some, they may view this downside as an upside, however, for those that regret their decision, tattoo removal can be both expensive and painful. An impulsive decision at the age of twenty, may not be what one believes in when they are forty. The same is true for those who have a name tattooed on them when in a relationship, only to regret their decision once they are no longer together.
CON: Health Risks

There are most certainly some health risks associated with tattoos, some being more serious than others. Certain inks have caused allergic reactions to occur, as well as bacterial infections. Although a respectable shop will be regulated, the possibility of infection can be significant. Of course, the worst case scenario is a dirty needle, increasing the risk of hepatitis or HIV.
