How is running good for mental physical health?

[objking]

I'm writing a research paper for a senior project and Id like to know the specifics on how running effects mental and physical health (http://www.healthknow.info/obesity_symptoms.asp).

I believe that completing research is an essential part of the process of writing a research paper. :rolleyes:

Have you ever seen a person who was long distance running crying or unhappy? There's your answer.

Running releases endorphins which makes you happy, called runners high. Physically it keeps you in shape, lol, that's not a lot of help, is it?
