The Ethics of Life Extension

buggieboy writes "The President's Council on Bioethics met this month to discuss Age-Retardation: Scientific Possibilities and moral challenges. The consensus was that "aging is a natural part of the life cycle, not a disease." Think Social Security was discussed?" Bruce Sterling's book Holy Fire is a good look at this issue if you find it interesting.

Predictably, the article spent some time covering calorie restriction as one of the few ways thought to significantly extend lifespan.

Calorie restriction has one BIG drawback: You are hungry all the damned time. You can ignore hunger for a while, but it never lets up. Without the imposition of some external discipline, you will eventually cave.

There is a possible alternative: Carbohydrate restriction. Carb restriction has nearly all of the effects of calorie restriction, without the gnawing hunger. From my own readings, and my own experience with low-carb diet, I have come to the following conclusion: One of the most important keys to living a long, healthy life is reducing the amount of insulin required by the body. (Of course, you need to avoid other causes of premature death, such as failure to wear seat belts, or being in certain areas of town after dark.)

It is not really clear whether insulin itself is the culprit, or blood sugar, or both, or some interaction of those things with other factors. But the evidence is quite clear, and growing. I have yet to see a nutritional study in which either the amount of carbohydrate or the glycemic load of the diet has been reduced without causing some improvement in health (although such improvements are usually attributed to some other factor, because of an almost universal bias on the part of nutritional researchers).

There may be some other things you can do to reduce insulin requirements, but the 3 most important seem to be:

1) Carbohydrate (easy) or calorie (hard) restriction.
2) Adequate and regular sleep.
3) Load-bearing exercise.

As near as I can tell, these three items are roughly equally important, as least according to the measurements I have available for my own responses to these factors. Of course, that's not all there is to it; in addition to restricting carbs, you need to limit or eliminate things like trans-fats. In addition to weight training, you should probably do some aerobics. As for sleep, well, that may be the hardest part for the caffeine-addicted geek.

I beg to differ

Good God, what dumbasses. Overpopulation isn't a problem in any western developed country. They're the ones who would use this.

Most environmentalists (the real ones, not the ones that put a "Save the Planet" bumper sticker on their SUVs) and population control advocates are VERY MUCH worried about overpopulation in "western developed countries". The amount of natural resources that a single person in a developed country consumers over their lifetime is significantly greater than the resources that a single person in an undeveloped country uses. Overpopulation in developed countries is an even bigger threat to the environment than overpopulation in undeveloped countries.

Regarding your comment about child limitation, you should probably clarify what you mean. Very few people are going to be in favor of manditory government-imposed child restrictions. However, changing the tax code so that any children over the first two doesn't give you a full dependent deduction might be a way of subtly encouraging people to keep their numbers down.

Drive dangerously.

[exp(pi*sqrt(163))]

Do you realise the consequences of driving safely?

1. You contribute to overpopulation. Maybe you don't realise that the human death rate is extremely and unnaturally low. By driving carefully you effectively cheat death and upset the cycle of nature.
2. You underappreciate life if you don't take risks. Part of the sweetness of life derives from the knowledge that we could lose what we have at any moment. Did you know that driving safely makes the biggest dent in the risk-taking we take and hence is the biggest reducer of our appreciation of life?
3. By choosing to drive carefully you increase your chances of suffering from diseases like cancer. The choice is up to the individual but many would prefer not to suffer a painful lingering death.

So drive dangerously folks!

Whoever wrote the paper seemed more worried about a _decrease_ in fertility than overpopulation. Many people can't wait until their kids move out of the house so they can have some of their life back before they get too old to enjoy it. Who would foster endless generations of children? Probably some but not many I think. They also seemed quite worried that the "cycle of life" that they already understand would change in ways they can not predict. I guess uncertainty scared them worse than mortality.

They didn't discuss in detail the benefits besides the obvious that it is what people want. Imagine a workforce that never ages. Everyone is in the prime of their life. Imagine the skills that employees could accumulate, the shorter learning curves because of previous experience. Imagine the increase in efficiency and productivity. Longer working life means people could save for retirement longer. Pension payouts would decrease. Workers could save enough to retire when they want and go back to working if they get bored which many do.

They also did not consider the possibility of rejuvenation for those who are already old. They talked of stretching the lifespan as if old age would also last longer, but with gene therapy maybe life can be maintained in its prime permanently or at least until you step in front of a bus.
