Do you like tattoos? It is a form of body modification using ink to create a permanent design.
I have seen tattoos, but i think they are unattractive.  Where did this practice originate?
Aparently It has been practiced since at least Neolithic times as there have been mummified bodies found with tattoos from that period.
i would have thought Africa, but you are most likely correct.  Isn't tattooing oneself an unsanitary practice?  Can you catch diseases from a tattoo?
Not anymore.  Modern tattoos nearly always require the use of a tattoo machine and procedures and accessories to reduce any risk to human health.
Is getting a tattoo painful?  And what about removall?  I have heard that they use a LASER;  That procedure must be painful.
I think it is pretty sore.  Tattoo removal is now more available.  Laser tattoo is a common method using techniques includin dermabrasion which reaches the deep layer of the skin.  There is also cryosurgery and excision which uses skin grafts.  All very painful I imagine!
