" Jason Griffin : Jason Griffin loves putting pen to paper, or fingers to keyboard, in the interests of adding to the already massive volume of online health and fitness information. After all, one never knows when one might just stumble across a rare nugget of wisdom not too many people know about. Apart from that, he specializes in turning boring scientific jargon into interesting, informative content that ordinary people can actually understand!."
