Engineering An End to Aging

Reason writes "Biogerontologist Aubrey de Grey has put forward a biological engineering plan to end human aging and co-founded the Methuselah Mouse Prize in recent years. Now he is finally getting some of the public recognition he deserves in an excellent David Stipp article at Fortune Magazine. If you ever wondered exactly how to go about engineering away the 50 million deaths due to aging that occur each and every year - and how to bring about a sea change in the scientific establishment - then this is the place to start. As an added bonus, I don't think you'll find a more succinct (and utterly British) answer to overpopulation objections to life extension than the one at the end of this article!"

      I may get flamed for this, but I'll say it anyway...This is why obesety is a problem in the U.S. People look for that miracle drug or easy-out diet that they can just "do" and see results that will last them a lifetime. The results from such things may last their lifetime, albeit perhaps shorter that it may have been if they made a lifestyle change. Keeping healthy and fit is not something meant to be done for short spurts throughout your life where you lose weight, gain it back, lose it again, etc. like a yo-yo. The key to successfully keeping your weight under control is to make a change that you'll keep for life and not tire of in a few months/years.

      Want to follow the Atkins Diet? Fine, but can you see yourself doing it for the rest of your life? If so, and it works for you, great! Stick with it! The key is sticking with something. Personally I may see people chomping on a T-Bone steak for breakfast and it makes me want to hurl, and I have a really hard time believing they'll stick with that for more than a couple years. Then again, some people with overeating issues may find the thought of never drinking sugary sodas ever again in their lives be impossible to imagine.

      The thing is, if they find some miracle drug that staves off aging, it'll just make it much easier for something else to kill people off, as it'll just be another excuse for people not to want/have to keep fit and healthy. And can you imagine the costs of healthcare and food with an overpopulated world of unhealthy, overweight people?

Obviously, you'll want to avoid driving it into ditches, keep it washed so it doesn't rust, give it the correct fuel, drive it in the correct RPM range, etc. However, you also need to do other preventative maintenance, such as changing the oil, changing the timing belt, maybe replacing the piston rings after 400,000 miles or so, etc. Basically, there are some parts of cars that eventually will wear out, like belts, hoses, and friction materials, and these need to be replaced. Just keeping the car clean and vacuumed isn't going to help when the brake pads wear out.

      This guy's theory is that regular biological processes in our bodies leave behind various contaminants or whatever, and need to be cleaned out occassionally.

The process of aging is still not completely understood and still has competing theories. The question of how much aging is pre-programmed and how much is random damage, especially to mitochondria, is not something that scientists have come to agreement on. While currently an appropriate diet is the biggest influence we can come up with to affect the life span of mice, that doesn't mean we won't develop better ways in the future. Our understanding of telomeres as well as oxidative damage of mitochondrial DNA, the production of garbage vesicles in the cell, the effects of hormones on development of aging etc, are all potentially going to provide mechanisms to modify life span potentials. Staying healthy and active is a good thing. Research on aging is not grasping at straws. It's the next logical step. If life extension were to be successful, remembering one's past would certainly become a more interesting endeavor. I suspect personal weblogs and other computerized storage would become very useful.

      5. Exercise. At least 30 minutes of strenuous exercise, three times a week. By strenuous, I mean you should have enough breath to carry on a conversation, but not enough to sing. If you know how, strength train three times a week. This is especially helpful for guys, as we tend to put on muscle mass easily. More muscle mass means a higher metobolic rate (even when sitting at a desk reading /.), meaning you'll burn fat faster.

      Try this for several months to a year, and see if you can reach your desired shape. If you do this for a year, and can't get where you want to be, resign yourself to the shape you have. Remember that you have done some great things for your health, and that is more important than a number on a scale. At this point, you can add the snacks back in - even the occasional sugary or fatty treat - but keep this routine going as a lifestyle. It would be very hard not to be healthy if you are eating right and exercising.

Making your body "immortal" wouldn't make you immune to death from the things that kill you now. It would just increase somewhat your chances of surviving. An auto accident, gunshot, or HIV virus would still end a life, but maybe just a bit later than now.

    Porn is going to encourage people to have children? Now there is a backwards through if I ever saw one. The problem isn't a lack of sexual desire.

Late interest in children due to working mothers is one, another is lack of religon, lack of agriculture (no need for 10 kids to work the farm), de-valuation of the family unit, female liberation, increased acceptance of homosexuality, etc. That isn't even getting into increases in impotence, or people just choosing not to have children.

    Here's a thought experiment for you - what if it's not that people don't want children, but that people want children later in life?

    that is only one small piece of the problem.

    Fertility drops off significantly in the 40s,

    Only for women.

    so convolving the dropping fertility with a shift in the age at which people want children will naturally lead to a lower birth rate. The total number of average *desired* children might not be changing at all.

    Ok, so say women can have babies until they are 50. I still don't think that will make a large difference in the grand scheme of things. It wont change 1.5 million abortions a year in the US alone, or how many children aren't born because of birth control. Again, I'm not saying these are bad things socially, but the are leading the US to a shrinking population.

    But then what happens when science is able to significantly improve the fertility of those in their 40s? A boom happens all over again.

    Unlikely. How many children are they going to have at 40? 1? Not only do you have to improve a women's chance to become pregnant, you have to do something about the greater miscarrage rate women have over 35.

    Like I said, it's a little naive to say that the birth rate trend won't change. They thought this back in the 80s, as well. I'm sure they had just as impressive reasons

    No, they didn't. Their reasoning was "People are fucking, people are going to continue to fuck". Sorry to put it so bluntly, but that was about the extent of it. I don't think in the 70's when "the population bomb" (or whatever the book was named) came out that they put much thought into what role abortion or womens rights might play with the population.

    as we have for believing that the birth rate will continue along its (relatively recent) trend. But despite our arrogance, we really haven't figured out human societal trends yet.

    Agreed it might not continue along it's trend, but I don't see any factors to stop it. Do you? Improved fertility will help, but that alone wont do it. Men and Women have to have the desire to have large families. They may have the desire to "do the deed" but they certainly don't want to deal with trying to raise a large family, at least here in the US.
