Scientists Identify a Potentially Universal Mechanism of Aging 359
cybergenesis2008 points us to a summary of research out of Harvard Medical School in which a set of genes known to affect aging in yeast was found to affect aging in mice as well. The genes, called sirtuins, perform two particular tasks; regulating which genes are "on" and "off," and also helping to repair damaged DNA. As an organism ages, the frequency of damage to DNA increases, leaving less time for the sirtuins' regulatory tasks. The increasingly unregulated genes then become a significant factor in aging. Realizing this, the researchers "administered extra copies of the sirtuin gene [to the mice], or fed them the sirtuin activator resveratrol, which in turn extended their mean lifespan by 24 to 46 percent." We discussed the plans for this research a few years ago.

I'm honestly scared of the day that they do figure out how to cure aging, because it will lead to an even greater stratification of social status and class. Most of the wealth in this country (and indeed most of the world) is concentrated with men who are over the age of 50-60 years. When they die, that wealth is then redistributed. Those people will be amongst the first to benefit from any such medical process; And if history has been any judge, that medical process will be expensive and there'll be little incentive to make it cheaper. The end result will be people who are born and work their entire lives, then die, never having had the opportunity to aquire wealth, because those who still have it aren't dying anymore.
This won't be something for humanity to celebrate. If and when the day comes, then we'll have to answer the question of what happens when numbers increase but resources decrease? And the answer will be in what kind of life is possible in that world. It won't be as good as the one you have now, I assure you.

If you can say younger for 50% longer that means there is 50% more time you can work. If they say raise retirement age from 60s to 80's and at 80 you feel like you are 60 then what can happen is there is more time you can contribute to social security thus more money in the system. Also longer time where the person is benefiting to the economy and less of taking what you deserve. You are under the impression that as people gain wealth most of them will horde it. While the truth is that they will try to spend it. So if the average joe can make more when they do retire with an exptected 20-30 years of their lives they will spend it more liberally, then if they had little.

Before they cure aging, they have to cure arthritis. What use is living to be a thousand if for 940 of those years you are immobile.
Arthritis is an interesting case, since it strikes humans after breeding age mostly, so evolution hasn't killed it off.

You're making the assumption that the amount of wealth in the world is fixed, and that the only way to acquire it is to get it from someone else (via death or other means). I think most people will agree that that is a false assumption.

If history is any judge, medical processes get consistently cheaper and more widely available.

What makes you think immortality leads to population increases? Actually, I think it's far more likely that it will lead to a decreasing population. I doubt that immortal people will continue to crank out kids decade after decade. It's more likely that an older population of people who have "been there, done that" will be done making kids, and we'll actually have an human extinction crisis in 1,000 years.
What that means is that immorality leads to a decreasing population leading to more resources for fewer people.

Oh, please. We'd be too busy stabbing each other in the back, fighting for what little scraps they do leave us, to ever do them much harm. Much as it has always been.
What kills them in the end (because nothing can last forever) will not be a rebellion of the poor. It will be their own stupidity as they will, inevitably, become bored, complacent, decadent and distracted - random misfortune will do the rest. It won't be till the very end, when their power is already good as gone, that angry mobs storm the palace and take credit for the people's great victory.

1) I would think that's because your dog's aging repair just turns off a lot earlier than yours does. We are all, from the time we're very young, accumulating "damage," it's just that it gets repaired more efficiently and for a longer time for some living things than for others.
2) From a certain point of view (through green colored glasses), the sky is green. That doesn't mean it actually is. I'm not sure you can say there's only one organism on earth except in the most metaphorical sense, and I'm too hard of a thinker to take metaphors like that very seriously.

I'm sorry but the facts [nchc.org] do not support this conclusion. The percentage of uninsured persons in the United States has been on the rise for some time and as of 2006 was at just over 20%. The percentage of people (workers and dependents) with employment-based health insurance has dropped from 70 percent in 1987 to 59 percent in 2006. Clearly, availability is going down. As to costs... You must not read the papers. Medicaid is about to go bankrupt due to skyrocketing health care costs.
Do you seriously believe the only way to acquire wealth is to sit and wait for someone to die and have it given to you? Sheesh.
I didn't say it was the only way. They could spend it. The majority of wealth (~70%) is owned by under 5% of the population, and given their spending habits, I just think it's far more practical to wait for them to die.

I thought the easiest way was being born into a rich family or winning the lottery. And as to "saving"... Honey, don't piss on my back and tell me it's raining; Most of us are living paycheck to paycheck, and we spend everything we get on basic necessities. We're not "consumer idiots" -- the technical term for people like us is fucking broke.

Bullshit.
You do realise that more countries in the world than Canada have "nationalised healthcare", right ? And that most of them have better $/result efficiencies, and healthier populations, than the US ?
About the only times I can think of where it would be preferable - from a healthcare perspective - to be in the US instead of a country with "nationalised healthcare", is if you're well-insured (which in the US implies being employed in a decent job), rich, or suffering from some incredibly rare disease where the only treatment available is there (and even that last one is borderline).
For the vast majority of people, and society as a whole, a system of "nationalised healthcare" is a vastly superior choice.

The GDP is "the total market value of all final goods and services produced in a country in a given year" [investorwords.com]. It is exactly the measure of the value produced in the economy. (Putting aside for the moment the broken window problem [wikipedia.org] and the need for a GPI [wikipedia.org].)
That "net income" is what's left of their gross profit of $100 billion [yahoo.com] after expenses, including payroll. So if your numbers are correct, each worker is on average creating $60,000 worth of value that isn't going to them, but goes to stockholders. (Of course some employees own some stock, but not enough to distort the general picture; it's not like GE is an employee-owned company.) That's bit higher than the $50,000 of my previous calculation but well within back-of-the-envelope tolerances. Thank you for the supporting evidence.
Rubbish. That "financing" is an artifact of our system, of the centralized control of capital. If I loan a carpenter a hammer, and he creates $25 of value an hour with his skilled labor, something is fundamentally wrong with a system where I can charge him $15 an hour for the use of my hammer.
Because that's not a fact, but a misconception. Stock owned by your pension fund is not owned by you. If you're invested in MegaBank's Growth and Income fund, and that fund owns 1,000 shares of Amalgamated Profits, Inc., there's not a share with your name on it, and you don't get to vote at their stockholder's meeting, MegaBank does.
These funds are mostly a means of putting more wealth under the control of Wall Street bankers and managers, any wealth that trickles down to fund participants is a side-effect.
