Yes. But up until two or so years ago no one in any mainstream capacity was doing any antiagapic research at all
Anti-aging research is always going on. How much interest mainstream science takes in it seems to be something close to a random walk.
For example, look at Alexis Carrel who won a Nobel Prize in 1912 and became more well known among both scientists and the general public not for his work that earned him that prize but for his apparently successful attempt to culture the cells of a chicken's heart for an indefinite amount of time. Many scientists attempted (unsuccessfully) to duplicate Carrel's work, even as many scientists visited his culture, and took for granted that his culture was real and there was some subtle difference. (It later turned out that it was likely due to accidental cell replenishment occurring in the culture feeding.)
A more modern example is the work with reservatrol which started being taken seriously in 2004.
Scientists have been working in the mainstream for this sort of thing for sometime. For more examples and a general history of related research, see David Stipp's "The Youth Pill"
So given this history, I'm more inclined to trust historical statistics.
where there has already been successful antiagapic work, it is being taken seriously, and biomedical prosthetics are getting more sophisticated over time over and above the norm, and organ-level cloning has a viable route to practical application, etc., etc..
I'm not aware of much successful anti-aging work. Do you have specific examples in mind? Caloric restriction and variations thereof seems in most species to increase the average lifespan but not increase the maximal lifespan.
I agree that prosthetics and cloned organs are likely to help a lot. To some extent, prosthetics are already doing this. Lack of mobility or difficulty moving can easily lead to problems. In that regard, artificial knees and hips have extended the lifespan in the elderly and substantially increased quality of life for many people. As we speak, artificial hearts are rapidly becoming usable for all sorts of people with severe heart problems while pacemakers and VADs are already standards.
For these things to together not result in the above-described projection being valid would require that several different underlying principles of the world as I understand it be false.
Could you expand on what these premises are? I'd be interested in seeing this chain of logic stated explicitly.

... not in any serious context, it wasn't. Given that most medical advances take roughly twenty years to get from the early "theoretical" stage to widespread adoption, looking at what was going on twenty years ago and earlier will demonstrate that there was quite certainly a widespread belief that all "anti-aging" research was non-existent, aside from palliative care for the senescent. Old age was cons...

I wonder how people on Less Wrong would respond to that poll?
