- “I don't want to achieve immortality through my work. I want to achieve
it through not dying.”
-
– Woody Allen
|

|
- What does science know about aging at this time?
- In the light of that knowledge what exactly can be done now by ordinary
people to retard, stop, or possibly even reverse aging?
|
4
|
- We all know what aging is, a process through we progressively become
more vulnerable to diseases and disabilities and eventually die. Aging is growing older.
- But scientists disagree not only
about what causes aging but what about it actually is.
|
5
|
- There are many theories regarding the causes of aging, each plausible in
its own domain, each with its own group of proponents, and each based on
credible research evidence.
- These theories are like the blind men of fable who feel only different
parts of an elephant. That is,
each aging theory is valid in its own right but presents only a small
part of the picture.
- A larger unified theory of aging is only now starting to emerge.
|
6
|
- Thoroughly investigate the major scientific theories of aging (14 of
them)
- Find out how they relate to each other, what they say in common
- Ask the question for each theory “If the underlying assumptions of this
theory are correct, then what can be done now to slow, stop, or reverse
aging according to this theory?”
- To combine the answers to determine what can be done now about aging
- Monitor the research literature of molecular biology, genetics,
genomics, etc. on a daily basis with an open mind
- Continuously update and revise my findings

|
- Oxidative damage
- The most traditional theory: that aging is due to accumulated tissue
damage due to oxidative stress created by free radicals.
- Cell DNA damage
- That aging is due to accumulated damage in cellular DNA, leading to
cancers, cell senescence or cell death, in turn leading to tissue and organ
deterioration.
|

|
- 3. Mitochondrial damage
- Mitochondria (energy-producing organells in cells) are critical to the
cell reproduction cycle and their DNA, different from the cell’s main
DNA, is particularly vulnerable to damage.
- Tissue glycation
- With aging, tissues become increasingly damaged and dysfunctional due
to cross-linkages with sugar molecules.
- Lipofuscin accumulation
- Metabolic product gunk called lipofuscin accumulates in cells and
inhibits their functionality.
|
10
|
- Chronic inflammation
- Chronic inflammation appears to be a core condition underlying many if
not most age-related disease processes.
- Immune system compromise
- Immune systems weaken with age increasing susceptibility to all kinds
of diseases.
- Neurological degeneration
- Neurological systems weaken with age causing loss of coordination of
other body systems.
|
11
|
- Declines in Hormone Levels
- Hormone levels run down with age and so do all of the body systems they
regulate
- Susceptibility to Cancers
- Risk of cell cancer pathology due to shift in gene expression increases
radically with aging
- Susceptibility to Cardiovascular Disease
- Cardiovascular diseases are the biggest killers of old people
|
12
|
- Telomere Shortening and damage
- It is thought that most of the diseases of old age come about through
cell senescence due to telomere loss.
Telomeres are the “caps” found on the end of chromosomes in
somatic cells.
- Programmed Epigenomic Changes
- Aging is a consequence of programmed shifts in gene expression that
happen throughout life.
- Decline in Adult Stem Cell Differentiation
- Aging is due to a slowing rate of organ regeneration because of
declining differentiation activity of adult stem cells.
|
13
|
- They are not independent
- E.g., oxidative damage can foster tissue glycation which, together with
programmed accumulation of INK4a can increase susceptibility to cancers
- Every week new research reveals more complex inter-relationships among
the theories.
- They all define important ways for looking at aging
- From the viewpoint of wanting to slow, stop or even reverse aging, I
don’t want to ignore any of them.
|
14
|
- The newer theories based on genetics, proteomics, molecular biology, stem
cells and epigenomics give more
powerful ways of looking at aging.
- Approaches that will enable us to live 150 – 300 years or more will be
based on them.
|
15
|
- In the last year I have identified four more candidate theories of
aging, reflecting sophisticated research in progress:
- Incorrect protein folding
- Accumulation of Progerin
- Gene mutations leading to hellicase abnormalities
- Aberrant mTOR signalling
|
16
|
- Focus on healthy people of any age and be concerned mainly with
here-and-now practical approaches:
- Ask the question for each theory “If the underlying assumptions of this
theory are correct, then what can be done now to slow, stop, or reverse
aging according to this theory?” Base
answers on research
- Define an anti-aging firewall for that theory consisting of
- Lifestyle patterns and habits, and
- Using dietary supplements
- Combine the firewalls to determine what can be done now about aging
|
17
|
- Macroscopic studies of large populations
- Like population of Okinawa
- Large population cohort studies
- Follow thousands of people for 10-30 years
- Controlled clinical trials
- Short, very expensive, specialized for drugs
- Animal experiments
- Mice and rats live 2-3 years, very good models
- In-vitro and in-vivo studies of cell populations
- Thousands of such studies, very specialized
- Synthesis and review studies
- Put together results from many studies in interpretative frameworks
|
18
|
- All the actions and supplements in the anti-aging firewalls are based on
one or more of these kinds of research
- Most are supported by several of these kinds of research
- For a few firewall elements, supporting research exists on all of the
above levels.
- E.g. value of exercise, impacts of consuming vitamin C, curcumin and
green tea
- New research results are constantly coming in
|
19
|
- Example: For the Oxidative Damage
theory of aging:
- Lifestyle firewall elements would include
- avoid circumstances that produce large number of free radicals (ROS) in
the body like X-radiation, UV exposure, ingesting heavy metals, eating
rancid food. Eat blueberries,
chocolate.
- Supplement firewall substances would include
- Antioxidants of various types which directly quench free radical
activities
|
20
|
- Example: For the Tissue Glycation
theory of aging:
- Lifestyle firewall elements would include
- Minimize eating substances having a high glycemic index, burned or
heavily browned foods.
- Supplement firewall substances would include
- Supplements that break up or inhibit formation of advanced glycation
endproducts like l-carnosine and benfotiamine
|
21
|
- Example: For the Programmed
Epigenomic Changes theory of aging: (looking at the role of NF-kappaB in
one such theory)
- Lifestyle firewall elements would include
- avoid circumstances and activities that trigger activation of
NF-kappaB, including many disease, stress and inflammatory processes.
- Supplement firewall substances would include
- Substances which inhibit the nuclear translocation of NF-kappaB – 36 of
them in the combined firewall program.
|
22
|
- Example: For the Immune System
Compromise theory of aging:
- Lifestyle firewall elements would include
- Sleep at least seven and a half hours a night on a regular schedule,
avoid chronically stressful situations, do mild cardiac exercise at
least a half-hour each day, avoid situations likely to lead to
infections
- Supplement firewall substances include
- Phyto chemicals and hormones which specifically enhance immune system
functioning as well as protect against infectious diseases
|
23
|
- Example: For the Telomere
Shortening and Damage theory of
aging:
- Lifestyle firewall elements would include
- Minimize stress, diseases, injuries, follow the general lifestyle
regimen.
- Supplement firewall substances would include
- Antioxidants, to protect against shortening
- Astragaloside IV or or cycloastragenol
to activate telomerase expression in body cells, possibly
immortalizing these cells and conferring longevity to the associated
organs.
|
24
|
- First: I started to pull this all
together in a draft of a book but I found relevant research discoveries
are happening so frequently that in May 2008 I decided instead to create
a comprehensive Anti-Aging Firewalls Treatise on the web. And in January 2009 a corresponding Anti-Aging
Firewalls Blog
- I update the blog almost every day and it contains over 134 major
postings and 123 reader comments
- I update the treatise more or less weekly
|
25
|
- Second: Although the anti-aging
firewalls for each theory are different, there is great overlap among
them so that in combination it was possible to identify an overall anti-aging
lifestyle regimen and an overall dietary supplement regimen, both based
on the current state of scientific knowledge of aging.
|
26
|
- Third: There is an immense
overlap between the research-based anti-aging lifestyle regimen, which
can be found online in my treatise, and conventional wisdom concerning a
healthy lifestyle in terms of sleep, stress minimization, exercise,
mental activity, social participation, good eating, good mental attitude
and so on.
- This conventional wisdom is not
only based on theory but is backed up by many long studies involving
tens of thousands of people
- I report frequently on these in my blog
|
27
|
|
28
|
- Fourth: most but not all of the
supplements in the overall anti-aging firewall regimen are well known,
taken by millions and have excellent safety records
- e.g., fish oil extracts, curcumin, glucosamine, calcium, magnesium,
zink, DHEA, vitamins C, D, and E
- Some are traditional Indian
or Chinese medicinal herbs that have also been extensively researched through
Western science
- e.g. ashwagandha, boswelia, ginger, astragalus
- A few are based on more
recent developments in molecular and cell biology
- e.g. alpha-lipoic acid, acytl-l-carnitine, astragaloside IV,
resveratrol
|
29
|
- fifth: it is clear that radical life extension—to beyond age 100 or
110—must depend on knowledge associated with the newer and more
sophisticated ongoing research in epigenetics, molecular biology, and
stem cells.
- Certain substances in the
anti-aging regimen may act powerfully toward this end, but what they can
actually do for human life extension will not be known for many years.
|
30
|
- Fifth (continued): Substances that might contribute to extending human
lifespans beyond the normal 110 year limit include:
- Use of r-alpha lipoic acid and acytl-l-carnitine to address cell
mitochondrial longevity and inhibit unwanted cell apoptosis
(self-destruction), and
- use of resveratrol or resveratrol homologs to activate the SIRT1 and
FOXO3 “longevity” genetic pathway, the pathway known to confer life
extension due to calorie restriction.
|
31
|
- Fifth (continued): Substances that might contribute to extending human
life spans beyond the normal 110 year limit include:
- Use of astragaloside IV or cycloastragenol to activate telomerase expression in
body cells so as to extend their replicative life spans, promote cell
renewal through differentiation of stem cells, and thus confer
longevity to associated organs, and
- use of green tea, curcumin, and other phyto-substances for their
powerful cancer-preventative effects and cardiovascular benefits that
operate through genetic mechanisms.
|
32
|
- Sixth:
- Research is revealing more and more cross links among the theories of
aging, and new theories are cropping up in the process.
- Like the outline of an immense approaching sailing ship still barely
discernable through thick ocean fog, the outline of a unified
understanding of aging is starting to emerge as the fog slowly falls
away.
- As this happens, I expect the anti-aging firewall regimens will continue
to become more sophisticated and powerful.
|
33
|
- Molecular biology
- study of biology at a molecular
level. Overlaps with biology, chemistry, genetics and biochemistry.
- Genetics/Genomics
- Multiple gene interactions
- Gene activation pathways
- Epigenetics/Epigenomics
- Critical information not in the genes themselves
- Proteomics
- Protein structures and functions
- Protein folding
- Stem cell science
- Induced pluripotent stem cells
- Adult somatic stem cells, autologous stem cells
|
34
|
- Every 7 years will see a doubling in the effectiveness of practical
available anti- aging interventions.
- Progress being driven by social, economic, scientific and technology
streams that are real today.
- The Law’s consequence is that, taking advantage of today’s anti-aging
interventions and the stream of new anti-aging developments likely to
come over the years, it may well be possible for a healthy person now
under 80 to break through the 122 human age limit and live up to
hundreds of years.
|
35
|
- When I first got involved with computers in 1951 there were only a few
hundred of us in the field.
Obtaining one of the first PhDs from Harvard in what was later
called Computer Science, I continued to participate in the “information
revolution”, making several key contributions over the years.
- Today, we are in a very early stage of a “longevity revolution,” also of
vast importance. The current
status of this new revolution reminds me of the computer revolution in
1955—the same excitement, rate of new ideas and discoveries, rate of new
people coming into the field, new practical applications, intractable
problems being cracked, and incredible promise for the future.
- .
|
36
|
- I am now 79 years old and see
longevity science as my main career for at least the next thirty years,
perhaps sixty. To help me get
there I do my best to follow the suggestions in the anti-aging lifestyle
and supplement regimens.
|
37
|
- Details of he theories of aging and the anti-aging lifestyle and dietary
firewall regimens can be found in my frequently updated treatise:
- ANTI-AGING FIREWALLS -
THE SCIENCE AND TECHNOLOGY OF LONGEVITY
- My companion BLOG can be found on the:
- ANTI-AGING FIREWALLS WEBLOG
- I post many interesting items relevant to longevity here on an
almost-daily basis
|
38
|
- Like my Treatise and Blog, this Presentation is a work-in-progress
- I will be revising it as time progresses to reflect new research and
changing perspectives
