Even with all the progress science has achieved, there are still unexplored aspects of the human body, like recently discovered saliva-producing organs. This ongoing discovery reveals just how unique and complex our bodies are. In fact, many features are found in only a small fraction of people, emphasizing the individuality of every human body.

Fingers and toes without nails

Imagining ourselves without fingernails and toenails is a scary thought, but some people are born that way. Anonychia congenita is a rare condition that results in a person being born without fingernails and toenails. However, this condition doesn’t impact their health in any way, and sometimes only some toenails or fingernails are missing.

A small hole near the ear

Having a small hole near the ear is a rare condition called preauricular pit. It can occur in one or both ears, although it’s most often seen on the right side. It is usually benign and does not pose any health issues.

Constant body odor

Constant body odor, also known as trimethylaminuria, is a rare condition with only around 100 cases reported. The human body contains a chemical called trimethylamine, which has a shy odor.

While the average person’s metabolism is able to process this chemical easily, some people’s bodies are unable to.

This results in the chemical accumulating in a person’s body and emitting a shy smell through their sweat or breath.

Unbreakable bones

A very small number of people possess extremely dense bones. This genetic mutation, called LRP5, was discovered after a man survived a car accident with no injuries in 1994. People with this condition have bones that are resistant to breaking and can even replace old bone minerals in response to new functional demands as well.
