PIERCINGS/TATTOOS

I like piercings and tattoos. When I was younger I loved piercings a lot. If I could i would have wore piercings in the lips, on the tongue, in the ears and in the nose (and another sites maybe). But now, perhaps not all of these, only in the ears and in the nose.
The tattoos are a different world. I like them but only with moderation. I hate how looks a boy with a lot of tattoos.
In the future I'll have a tattoo of an atom on the back.
I know many people who wear tattoos or piercings and one of them did it when he was 14. I tink that you have to be more mature to think about the consequences of it... a tattoo is a thing that you can not remove without problem, it's forever.
I'm going to wait some years and then I'll decide if I can wear or not the tattoo.
