According to "Ripley's Believe It or Not!" comic strip:

"Researchers who set a longevity record for the life of a mouse through the creation of an anti-aging treatment get a piece of the million dollar prize offered by the Methuselah Foundation.  It's all in the hope the experiments will lead to human immortality!"

My Stance: This would not be good.  I'm going to leave aside the religious implications and discuss a few other things:

1) Max Population: If humans ever did live at least three times as long, we would soon reach a state where the job market in almost every field would be saturated.  After that, overpopulation would soon follow. 

2) Leading to Overpopulation: Does one honestly believe the common human could withstand not having sex to help control the population?  Somehow, I doubt it.  My view is "sex after marriage only for children," and it has become extremely unpopular these recent years.

3) Speciesism: The average human believes him or herself to be the most important species on the planet.  By definition, we're still animals and still subject to the ecosystem as a whole.  It is my view the human ego needs no further boost, though it certainly needs a large deflation.

4) The Point? What's the point in living more?  Does that not destroy most of the purpose of religion?  People should live in their time and not try to extend it unnaturally.  I promised I would not touch on religion, as that unleashes too many topics to keep this entry under a page.

In the end, the topic rubs me the wrong way.  This is going too far by playing too far under the hood of God's universe.  Still, I can't help but wonder if others have felt the same way and asserted the same arguments in response to what was "advanced" medicine in their day and age.  If so, that doesn't leave me much room to stand.
