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 fishy 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 fishy 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.

Extra taste buds

Some people are born with more taste buds than regular people and are called supertasters. People born with this ability are sensitive to bitter flavors in foods like coffee, chocolate, broccoli, etc. About 25% of the population is born with this ability, and women are more likely to be supertasters than men.

Excess hair growth

Werewolves are just something we hear about in scary stories, but this condition will make you believe they exist in real life. Also known as werewolf syndrome, hypertrichosis is excessive hair growth all over a person’s body. It’s so rare that only 50 cases have ever been documented. The causes of this are not well known, but it frequently runs in families and can be present at birth.

Seeing more colors

People with tetrachromacy have the rare ability to see extra colors. All of us have photoreceptors in our eyes that help us see light and colors.

The average person can only see colors through 3 photoreceptors, namely blue, green, and red. But people with this condition can see through 4. Women are more likely to have this condition, and around 12% of them have this extra one.

The Absence of Tonsils

For the most part, removing tonsils is done at an early age for kids. But adults can have them removed too, and it is possible to live without them. Tonsils are located at the back of your throat, and their job is to keep germs from coming into the mouth.

For most people, they usually get smaller as we get older, but sometimes they don’t — and this is when they become infected and need to be removed through a process called a tonsillectomy.
