Okay, they aren’t unbreakable, but they’re much denser than normal and that counts for something. A mutation in the LRP5 gene not only bakes your bones with power and makes them hard to break, but it makes your skin less prone to aging. Sounds like a pretty good combo. On the other hand, people with this condition tend to have issues with joint replacements if they haven’t been watching their weight.
Imagine trying to do surgery on Superman’s bones. Even if it’s something he needs, you’ll be going to have to put a lot of effort into it.
Long Palm Muscles
Known in the scientific community as palmaris longus, this is a muscle that is useful for climbing trees. It's not something that most of us need that much anymore, but there's a relatively good chance you have it. To see if you have it, place your arm on a flat surface like a desk and touch your thumb to your pinky finger.
If you have a long palm, the muscle and tendon will pop out of your wrist. I definitely have it, which isn't a surprise. I have some dang long hands. If you do have them, go do some climbing and use what nature gave you.
A Gene That Means You Need Less Sleep
There are a few famous people in history who benefit from this gene. The DEC2 gene basically shortens a person's sleep cycle, so they feel just as rested on less sleep. Illustrious figures like Winston Churchill, Nikola Tesla, and Margaret Thatcher have all used this gene to get tons of work done while other people needed their sleep.
Of course, those people might not have called it a blessing, no matter how nice it sounds to us. Instead of the normal eight hours we all SHOULD be getting, these people got by with between four and six hours. Despite the number of figures who have profited from it, this is a pretty rare mutation.
An Extra Hole in Your Head
Having a little hole near your ear is called a preauricular sinus, and is discovered during a newborn's first examination. These small pits develop due to developmental defects of the first and second pharyngeal arches, or, you know, the ear bits. They can occur on one side or on both, but for the most part, they're harmless. As long as you don't use them for earrings. We really don't recommend that.
However, these kinds of ear malformations can sometimes be associated with renal anomalies. Even if they do become a problem, getting them dealt with is usually no big issue.
An Extra Neck Rib
More prevalent in women, having an extra rib near the cervical spinal region (or “neck” for us dum-dums) is known as a cervical rib. Somewhere between one and three percent of the people in the world have a cervical rib on one side or both. They may reach down to connect to the first rib, or they may not be fully formed.
Often the bone is tiny and hard to notice even on x-rays, but they can sometimes cause complications. A cervical rib means higher chances of nerve or blood vessel compression between the rib or its muscles since the ligamentous connections take up a smaller space.
