Maybe mind exercises have some benefit? Like the ability to control one's inner-organs through the use of a relaxed and controlled focus. I have also heard of monks being able to massage and manipulate their organs like you can with your biceps, and why not the heart is nothing more than a muscle that can be controlled. I think these monks clearly prove that by lowering their heart rate and at the same time raising their body temperature.

IMO one of the main goal's of meditation is to help the body stay healthy and live long. I think that has a lot more benefit in life than the ability to kick butt.

Can anybody here achieve this?
