Tattoos

Tattoos represent severals stuff, most likely representing the thing that a human want or did, here's an example "Harm None" and in between the two words is the symbol for the three phases of the moon, which also represent past, present and future, it's more than an art or fashion style in the people who do this it is a symbol for the people who have tattoos, also cultural because of the meaning which the tattoos represent, could be different for many people, depending on the culture here's another example of people opinions:
 "the tear drop used to mean you had killed someone, then it came to mean you had killed someone while incarcerated. in australia it means something totally different. they mark child molesters with that so everyone knows what they did and you can feel free to beat the daylights out of them"

In my opinion I wouldn't do any tattoo because it is a waste of time and money and I don't belive in any culture that represent via tattoos it is illogical etheir ethical a tattoo means nothing for me just a waste of skin
Without mentioning a big list of diseases which involves the tattoos like hepatitis or Aids for using the wrong equipment or for not cleaning them.

Here's an example of a tattoo.
