Here's an example of why I think there is more stopping the policy makers than just the "can we do it" question. It's the "should it be done" question. Read this piece of trash:
http://www.livescien...ity_social.htmlI guess we need to do a better job of pointing out fallacies that much of the public adopts such as the following:
Bioethicist Daniel Callahan, a cofounder of the Hastings Center in New York, didn't share Stock’s enthusiasm. Callahan’s objections were practical ones. For one thing, he said, doubling life spans won’t solve any of our current social problems.
"We have war, poverty, all sorts of issues around, and I don't think any of them would be at all helped by having people live longer," Callahan said in a recent telephone interview. "The question is, 'What will we get as a society?' I suspect it won't be a better society."
First the author states his doubt that longer life will fix the human condition plagued by war and poverty. Well, he might be partially correct, but having a longer life will likely mean a more productive life as well (less age-related cognitive decline and more years spent working). So I suggest that additional longevity could only help those factors that he is concerned about. In fact, as the first author mentioned, I think longevity would make society a lot less "desperate" as the time limit for accomplishing one's goals would be extended. To say anymore here would just be preaching to the choir, but this represents one fallacy that needs to be addressed.
Others point out that a doubling of the human lifespan will affect society at every level. Notions about marriage, family and work will change in fundamental ways, they say, as will attitudes toward the young and the old.
Regarding the final few words, "attitudes towards the young and old", yes, these will probably be challenged, but I think for the better.
The rest of the article goes on to persuade people that change is bad:
Furthermore, if life extension also increases a woman's period of fertility, siblings could be born 40 or 50 years apart. Such a large age difference would radically change the way siblings or parents and their children interact with one other.
"If we were 100 years younger than our parents or 60 years apart from our siblings, that would certainly create a different set of social relationships," Hackler told LiveScience.
Anyway, prometheus, as the final sentence points out, there is more limiting anti-aging research than just the question of feasibility -- having evidence to prove that lifespan can be extended:
"If this could ever happen, then we'd better ask what kind of society we want to get,” Callahan said. “We had better not go anywhere near it until we have figured those problems out."
The attitude expressed in the reference article may be stopping major donors of the size of Gates. Perhaps he shares some of the same reservations as mentioned in the article. This is something that we can address.
