Ki is a fundamental concept of traditional Chinese (oc)culture. Ki is believed to be part of every living thing that exists, as a kind of "life force" or "spiritual energy".

Like all traditions especially traditions involving magic, it has its critics. But, a lot of modern magical systems adopted the idea-- psychics commonly use the term "energy" for the way they interpret things on the extra-sensory, and the idea of psychic energy manipulation has become one of the fundamentals of psionics. They usually call it "psi", though. I personally consider psychic energy the keystone of all magic, but do keep up the vocal critical thinking.

i have two qeustions

1.can you run out of ki?

1.can a young child use ki?

1.) Not that I've heard. Acupressure is an alternative healing crafted to fix ki "blockage", though, and sure if you do something too much you'll feel strain.
2.) I don't see why not -- by some accounts, children use ki with much more vitality but less control than adults.

i see so if if i wanted to teach my child how to use ki he wouldnt pick it up qickly but would get it eventualy
