Incredible how it sounds, but human chimeras exist and not only in the stories.
Being your own twin is a rare genetic condition which can result in multiple health issues and persisting problems.
Usually, a person affected is completely unaware of this because the medical workers are completely unprepared to deal with such an exotic condition.
This condition is so rare that merely a few cases are found across the world.
One of the most notable representatives of it is a Californian entertainer and model, Taylor Muhl.
The human chimera is actually merging with own twin while still being in the womb which can result in various abnormalities.
For Muhl, who is absolutely gorgeous the condition resulted in the hostile autoimmune issues which she suffers in a full duration of her life.
Unfortunately, Muhl is caring two sets of DNA so the immune system of an each side of her body started to attack each other.
Despite her health issues she has a successful career and keeps on inspiring general public with her energy and altruistic personality.
