Real Super Powers

I've been trying to look for a way to explain my innate ability to fight, and immortality, and I came across chi, or ki as it's called in Japan. In some comic books, it gives the person invulnurability as long as they can focus, long life, and awesome fighting ability. I looked up real life examples and found the following: a guy who could through a needle through glass, a guy who could start a fire with the force of his chi, and a martial arts person who knocked a guy with the force of his chi. Some of this is on Youtube. So I thought, what if my power is just a subconscious manipulation of this life force? Tell me if this makes sense. Comment?
