I am one of those that has a tattoo. Why? Why not? It's not big, can be hidden, and it doesn't hamper my business side.
My I have family members who wear 4 to 5. I do agree with you on there is a limit, and some ladies just don't need to have them everywhere; like my sister and niece. Both of them are way overboard.
My husband has 4 BIG colorful ones, doesn't bother me. He is a computer geek who has his own business.
I guess it is a trend, no more so then foreign cars with big wings and an exhaust pipe that can house a family of 5 squirrels. The same goes with girls wearing jeans so low, their "parts" nearly show.
It's all a trend. And yes, tattoos can now be removed safely and really well.
