Permanent tattooing: How does this occur ?

A TedEd video on how permanent tattooing occur.



Personally I am against permanent tattooing. Not that I have anything against tattooing but everything against permanency of it. What if you do not like it after few years? What is the need to alter your look permanently? I would theorize the most vocal proponents of permanent tattooing are deeply insecure about something. They might not be in tune with their own appearance or psychological image.
If a pro tattoo individual is enraged by my words, then the above theory holds good for them. If they are not, then every theory has a corollary. They are the ones who deserve to have permanent tattoos.
