Robert Bradbury on Longevity Research
Robert Bradbury posts a great deal of very interesting material to the Gerontology Research Group list. Like Aubrey de Grey, he has a "get it done" mindset that focuses on the end goal of healthy life extension, and raised money to make an effort back in the 90s - all of which is somewhat rare in aging research, sad to say. Not enough decisive action, not enough attention to raising funds and changing minds, and far too little straight talk.
It's always worthwhile to note that present best efforts are the next step on a long stairway; looking back, one can always find analagous previous best efforts. Progress is a matter of each round of initiative and fundraising producing greater impact and results than past efforts.
Just recently, Bradbury responded to a fellow looking for advice on fundraising for longevity research in the face of an adverse reactions from potential funding sources ("longevity research is bullshit", "no-one knows why we age," and so forth), from which these thoughts are excerpted:
For example there are books like Caleb Finch's "Longevity, Senescence and the Genome" (922 pages, 160 of which are the bibliography) which clearly documents variances in longevity of many species and goes into some of the causes of aging and why some species may live longer than others. There is Steven Austad's "Why We Age" (244 pages) which explains the evolutionary biology of aging.Aging and longevity research is not "bullshit", but it should be realized that for a number of reasons one can view "aging research" as a situation similar to that of the 1986 movie with Tom Hanks and Shelly Long, "The Money Pit".
One thing that Aubrey has done a good job of pointing out in various ways is that indefinite longevity does *not* violate any physical laws. And as Steve Austad is good at pointing out (based on Medawar & Williams) there are reasons that "nature" has not handed us a genome which allows us to live indefinitely. And as I like to point out achieving the "impossible" tends to be a matter of timing. No amount of money in the world could buy you your personal genome sequence in 1990, yet today the $1000 personal genome sequence is on the "to be developed" list of the NHGRI (at NIH) (as well as a number of companies who see it as a $$$ milk machine).
I will be more than happy to stand in front of anyone claiming that pursuing "indefinite longevity" is "bullshit" and rip them to shreds (there are some images that were probably cut from Sopranos episodes that come to mind here...).
...
It is useful to keep in mind that Larry Ellison, through the Ellison Medical Foundation, has probably personally dumped between $100 and $200 million into aging research and it could easily be argued that there is little to show for it. One of the key reasons for that, IMO, is that the money was spent within a "research" framework rather than a business (solution) framework. If we had days for discussion we could examine how much of the money ($500-800 M/year???) being spent by the NIA is being spent "effectively".
One way to prevent money from being spent wastefully is to have a clear goal up front to *produce* a deliverable -- where the deliverable is *not* a set of words on a piece of paper (the byproduct of most "research"). There should be a well defined set of steps to get from the current science to that deliverable. It could be argued that a lot of the "sunk" funding into aging and longevity research was spent before the science was as robust as it currently is so claims regarding "longevity bullshit" (which even I may have made a decade ago) are no longer valid.
...
I strongly urge you to *not* specify "research of (or on) longevity". The science and theoretical basis of "longevity" is well understood. The mechanics of how it is accomplished in specific species (tortoises vs. sequoia trees) is less well understood. And you could easily dump tens to hundreds of millions of $ into researching how each long lived species achieves longevity (bats, elephants, whales, tortoises, lobsters, geoducks, etc.) and have very little to show with respect to extending human longevity.

I second that quote from the article. Ive dedicated my life to life extension. (What else would a person dedicate their life to first and foremost anyways?)
Im looking for restless people with a nack for marketing to collaborate with me on ideas. Contact me right away if thats you or you have ideas on where these people are!!

RESPONSE:
I have a different view.
My sense of it is that relatively small minorities of people are motivated towards extreme longevity. But, I certainly agree that there are probably many who are sufficiently curious about the prospect of enjoying life into the future.
When I was a child during the 1930s, I was highly motivated to want to travel in the 25th Century A.D. in the company of Buck Rogers and Wilma, and my enthusiasm remains the same, undiminished to the present time.
In my view, Ellison Medical Foundation merely failed to maximize its longevity mission by failing to establish a bolder, more imaginative game plan. That is, the $100 million or so could have endowed a “Nobel-type” annual prize, in which the endowment interest income is remitted to the oldest surviving human being, with similar consolation prizes to a few of the runner-ups, or even to juniors who have made a significant contribution to wellness and enthusiasm for life.
Wasteful? Of Course, what with millions of people dying from disease every year, but
not wasteful at all, if the objective is to generate a widespread enthusiasm and general interest in rewarding longevity.
A Nobel-type money prize to the “Oldest Surviving Human” could be an annual media event, equal to, or exceeding, all of the Super Lotto extravaganzas put together.
In the game of “Ellison Longevity,” every living person is automatically “a player,” at no cost other than trying to achieve and maintain better health.
Well, that’s my view. Rebut it, if you can.

Aging appears to be related to the ability of human cells to replicate in a mechanism called mitosis. About 90% of a cell's life span is devoted to mitosis. Cells are exposed to damaging free radicals and oxidants, as well as various cytokines. Each time a cell replicates into two new cells, one of the new cells dies so that the old cell is replaced by a new cell. The new cell withstands the damaging attacks better than the older cell so that an organ, such as the liver or endocrine organ survives for many years or humans would die in childhood.
We know that one-celled ciliates or paramecium replicate about 200 times before showing signs of aging. If all cells in the human body can be continuously duplicated, a human could live to 150 years old or longer. It has been demonstrated that cells stop replication for various reasons, some of which appear to be related to the length of the telomeres, which are the ends of chromosomes in a cell's nucleus.
A recently discovered enzyme called Telomerase has the ability to keep the telomeres from shortening, as they do during each replication. Telomerase also has a function that keeps cancer cells alive so that cancer cells can be immortal. Cancer cells die only when the human host source of nutrition dies from the cancer or when radiation, chemotherapy and surgery destroy the cancer.
The human body produces Telomerase. However, as one ages that production decreases significantly. It is postulated that if a drug can be found that stimulates the continued production of telomerase, then a human will survive additional years.
Telomerase that is developed by a pharmaceutical company that could be foreign to any human, may stimulate the growth of cancer. Only Telomerase produced by the individual human appears to be safe for cell longevity and cell replication, which enhances longevity.
Research dollars spent to increase longevity have been somewhat wasted, because there does not appear to be a coordinated effort. By that I mean an individual or committee dedicated to visiting each research lab given research dollars, so that suggestions for continuing the research are made during the time allotted for the research before funding is lost. Too much time is lost waiting for longevity conferences or published research articles to appear, wherein research is reported.
At the University of Pennsylvania, as well as other institutions, emphasis has been placed on an integration of disciplines. Medical research, engineering research and even nanotechnology research have been reprogramed to coordinate their efforts. The days of a single research lab with one or two scientists working on one aspect of a hypothesis must end. There must be an integration of all research for anti-aging. If that can occur, then research funding will have less tendency to be wasted and the time to obtain answers will be shortened.
A person or committee to coordinate the research must be well educated in the field of anti-aging and research scientists must be willing to share their progress immediately, with credit given to each scientist involved.
