The way it is presented to fresh minds (especially those over 40) is most important. I suggest approaching the one whom you judge will be most likely to be readily persuaded by it and get them on your side and convinced, before you spring the news to the others. What you don't want, is for two or more to be opposed to the idea or think it is the idea of a crackpot, and the express that opinion to the others --- becuase of peer pressure it could put the idea dead in the water. Something coming from an MD who is also a professor, like Dr. Abraham or Dr. Miller, carried alot of weight in convincing me at the onset.
