This isn't so much about liking or not liking the look of the tattoos themselves.... We all have different tastes and what one person will perceive as beautiful, another will perceive as ugly, and that's fine and not my point.
My issue is with tattoos' permanence, and why (however, beautiful the person might think their tattoo is) a large number of people mark themselves very prominently (I'm thinking full arm, chest, leg etc. rather than a small dolphin on the heel type of thing or a name of a loved one somewhere discreet) in a way they'll never be able to erase... How can they be confident they won't change their minds as they age, and fashions and their tastes change?
Surely it would be like buying a piece of clothing that you're forced to wear for ever, or exchanging your hair for a permanently attached wig (that you may love now, but will you want that hair style in 20 years?)
In short, I get why people want body art... I just don't get why they want it permanently.
