The meeting largely comprised a series of half-hour
discussions, each led by a different participant who is a world leader in
his or her field. The overall moderator of the meeting was de Grey. Areas
covered included reversal of cell loss (especially in brain, muscle and
various glands), reversal of somatic DNA damage or its effects (including
mitochondrial mutations), reversal of decline in cellular proliferative
potential (in various cell types, including fibroblasts and osteoblasts)
and reversal of accumulation of cross-linked, unrecycled macromolecules
(both in the extracellular medium and within lysosomes). All these topics
have seen very significant biotechnological advances in recent years,
which have attracted too little attention in the highest-profile science
media. They lead us to believe that a dramatic extension of maximum
lifespan in mammals may be much nearer than many of our colleagues
contend.
Each half-hour discussion revolved around the expertise
of a single participant, the discussion leader, who began their discussion
with a few-minute introduction. The "product" of each discussion was a
list of projects which (a) are directed to reversing the aspect of aging
that was discussed, (b) either are ongoing already (though in need of more
exposure/funding) or can be initiated now at a realistic funding level,
and (c) could be planned as engineering rather than basic science
projects, i.e. it can be stated in detail how they would be seen to
completion (though unforeseen pitfalls are recognised to have a chance of
arising).
Following these discussions, the meeting addressed the
relevance to society of progress in the various research avenues outlined
above, and the consequent implications for science policy in the USA and
worldwide. Stock led the analysis of these matters. Faced with increasing
hype about anti-aging breakthroughs in the popular press, the reaction of
many professional biogerontologists has long been to declare that any
substantial increase in the maximum human lifespan is absolutely
unachievable. This has led to promotion of the concept of "successful
aging", by which is meant (in the extreme) avoiding all age-related
dysfunction until somewhat past the present average lifespan and then
dying in one’s sleep while in good health. The desirability of "successful
aging" as a goal of biogerontology research has been widely embraced by
professionals, but we believe that it is grossly misguided. Not only is it
biologically much more implausible than extending maximum lifespan, but it
is also very far from what elderly people actually see as desirable—the
fitter they are, the more they wish to live, irrespective of how old they
are. Thus, the public and professional policy regarding biogerontology
research is in severe need of re-evaluation, since it does not presently
reflect public aspirations. The urgency of such a re-evaluation is
heightened by the fact that reversal of aging in rodents will occur long
before such technology can be applied to humans, but will trigger an
immediate shift of public perception regarding the malleability of human
aging, with dramatic consequences for society.
