Body modification can be in the form of piercings, tattoos, implants and/or removing parts of the body or even changing the shape of a body part. In extreme cases people have been splitting their tongue, tattooing their eyeballs and even implanting horns into their head.
Some religions or tribes also have body modification as a sign of their skill or bravery. For instance, some tribes stretch their necks and lips.
In the future people may even start modifying their genes to make them more muscular and so on.
What do you make of body modifications?
