I believe there is a linear relationship between incidence of suicide with our world's increasing leisure-time sedentary behavior. The fundamental problem with suicide is not knowing "this isn't all there is," or "there is something greater outside ourselves" and the realization if one were to live 100 years, life would still be too short. The search for such greater things is reason for an adaptive evolutionary life.,(reply>), Your comment is why I like to read the comments first before the podcast particularly if the podcast is long. Yours is so right on. I used to read a lot of vampire literature to understand the problems of long life. My favorite is a series by Chelsea Quinn Yarbrough. Her hero is Count Saint Germain who actually has some connection to reality, with him being spoken of in European circles royalty. He had to keep changing his identity every 30 or 40 years reappearing as a nephew to claim his property. Also having to deal with those he loved dying. In our future of long life this will not be such a big problem for us as those around us can be long livers too. There is still the problem of constantly keeping up with all the new stuff and changing with the times. That will always be with us.
