This blog entry is in response to the wager challenge in Jim Watson’s post Aging science wager challenges and prizes open to readers of 8 April, 2013.  As you will recall, $2.00 is the total at stake.

Normally, Jim and I see quite eye-to-eye when it comes to the science issues covered in this blog, as you can discern from previous blog entries co-authored with Jim. However, when it comes to these two wager issues, I think Jim is egregiously off base.  He is off-base in a very fundamental sense, that is in the very way he poses the wager issues. It is too strong to assert that his tricky formulations of these issues are just sheer baloney. Perhaps creamed pastrami or corned beef spam is a more appropriate metaphor.

Wording of Jim’s original challenge is shown in ordinary text and my responses are in italics.

“Vince: As I get to know you better, I now feel comfortable enough to create some “intellectual hormesis” between us.  Just like physical stressors are good for our bodies, I think that intellectual debate is good for our minds.  A fun way of creating debate is to do what Stephen Hawkings famously does with his astrophysics friends…..they make a wager.

I would like to propose that we make bets for a large sum of money… dollar per bet.  I would like to propose that we wager on the following controversies which I will “stir up” as follows:

I accepted Jim’s wager offer and promised this response.

  1. Wager #1 – What is the most important signal?  ROS, nutritional substrates, or hypoxia?  [i.e.ROS signaling (via Nrf2) vs Nutritional & Hypoxic Signaling (via HIF-1a and SIRTs)] (I, Vince, think this refers to anti-aging interventions)

Based on what I have read of your writings, I believe that you are convinced that the key to understanding aging and doing something about it lies in the Nrf2 transcription factor.  Am I correct?  You are arguing that all efforts to do something about aging must increase the cytoplasmic-to-nuclear translocation of Nrf2 where it can bind to of the anti-oxidant response elements (AREs) at promoter sites.

Based on everything I have read, I disagree with the above fundamental premise and will “debate” with you that “ROS signaling” is not the most important signal. My premise is that low nutrients (i.e. redox signaling due to low glucose, fatty acids, and amino acid substrates) and low oxygen (hypoxia) are the most important “signaling mechanisms” that turns on longevity mechanisms.

Proposal:   I propose that we make an “intellectual wager” for the lump sum of one dollar.  To allow time for the debate, the winner will be “paid up” at end of 2013.  The “wager” is on which is the most important “signaling mechanism” for longevity – “ROS signaling” or “Nutrient/Oxygen signaling.”

I know Jim well enough to shy away from taking on his formidable intellect directly. So I am going to argue that “ROS signaling” and “Nutrient/Oxygen signaling, along with a number of other signaling mechanisms are equally important for longevity. In other words, the question itself is dumb.  Therefore I am proposing that the outcome of this wager be a tie. My argument hinges on what is meant by “importance,” and I can best start out with an analogous question.  “What is most important for the long-term trouble-free operation of an automobile, the engine, the transmission, or the wheels? It is tempting to answer “the engine”but in fact the automobile will not operate without any one of these components. The same is true for the question at hand. The body will not operate and die without both ROS signaling and Nutrient/Oxygen signaling.   Longevity, in fact the continuance of life of an organism, depends on multiple pathways, these two along with many others.

Perhaps the gist of Jim’s point is to ask which pathway is most important from the viewpoint of enhancing health and longevity.  That is, if we want to create practical health and longevity intervention, is it better to go after the ROS signaling or the Nutrient/Oxygen signaling pathway.  There, I would submit the answer is probably both, and that it is unclear whether one is more likely to prove amenable to effective interventions than the other

It is true that I have been an exponent of the importance of ROS signaling, but in fact so also have you been so, Jim. The arguments for the importance of ROS signaling have been laid out in multiple past blog entries and in my other writings and presentations starting with three often mentioned entries: The pivotal role of Nrf2. Part 1 – a new view on the control of oxidative damage and generation of hormetic effects, The pivotal role of Nrf2. Part 2 – foods, phyto-substances and other substances that turn on Nrf2, and  The pivotal role of Nrf2. Part 3– Is promotion of Nrf2 expression a viable strategy for human human healthspan and lifespan extension? The latter two blog entries are among those which suggest that this pathway offers significant opportunities for health–generating and possibly longevity enhancing interventions. I think Jim will agree that ROS signaling and the NRF2 pathway are key to several health and possibly longevity inducing processes of hormesis.  This, too, is pointed out in multiple blog entries such as in Multifactorial Hormesis – the theory and practice of maintaining health and longevity and in the PowerPoint presentations contained in the blog entry Multifactorial hormesis II. A nice thing about this pathway is that there are numerous interventions that can kick it off including eating a number of plant-based substances, radiation of various kinds, and taking very small doses of a number of toxic substances.

I think that the same importance, both for survival of an organism and for health and longevity inducing interventions, can be made for Nutrient/Oxygen signaling so I am not in a position to claim outright victory in this wager. Without doubt, low oxygen turns on hormetic hypoxia signaling as pointed out in the same blog entries related to hormesis.  And the hypoxia-induced hormesis can be health-inducing and possibly longevity-inducing. Interventions that can produce health effects related to glucose include calorie restriction(ref), exercise, alternative day fasting(ref), taking Resveratrol to stimulate SIRT(ref), and climbing mountains to achieve hypoxia.    

Personally I practice interventions in both categories, related to ROS production and to Nutrient/Oxygen signaling.  Some interventions such as vigorous exercise relate to both pathways.  Also, a new favorite set of interventionsof mine is utilizing cold shock, such as induced by leaving windows open in the winter here in New England while naked. Some day, when we “get the hormetic stressor dose right”, we might indeed discover that activating one particular set of stress pathways is clearly the best single way to go.  For now I am betting on both of our candidates and all others I can easily activate.

Wager #2 – What is the most important cellular adaptation mechanism? (i.e. hormetic response).  (i.e. anti-oxidant response element upregulation, unfolded protein response, mitochondrial biogenesis, DNA repair mechansims, autophagy, etc.)

Based on what I have read of your writings, I believe that you are convinced that up regulating the anti-oxidant enzymes is the most important cellular adaptation mechanism.  Am I correct?  According to you the most important “hormetic mechanism” is the up regulation of the anti-oxidant enzymes in response to low doses of “ROS” or through administer of phyosubstances that interact with the cysteine side chains of Keap1 (and Nrf2) and thereby effectively act as “ROS mimetics” to up regulate the AREs.

Based on everything I have read, I disagree with the above fundamental premise and will “debate” with you that up regulating the anti-oxidant enzymes is NOT the most important cellular adaptation mechanism.  For the sake of an intellectual debate and a one dollar wager, I will propose that activating autophagy is the most important cellular adaptation mechanism for longevity, not anti-oxidant enzymes.  Specifically, I am talking about “getting rid of bad mitochondria” by mitophagy, rather than trying to “mop up” all of the excess baseline ROS produced by these “leaky mitochondria”. I don’t think you can make enough anti-oxidant enzymes or ingest enough “exogenous antioxidants” to make a dent in the baseline ROS levels.  Both exogenous antioxidant use and endogenous antioxidant up regulation are futile.  Getting rid of bad mitochondria (the source of the excess baseline ROS) is NOT FUTILE. This is why I want to have a debate with you over the next year on this.

Proposal:   I propose that we make an “intellectual wager” for the lump sum of one dollar.  The question is what is the most important cellular adaptation mechanism? (i.e. hormetic response) that promotes health and longevity.  (i.e. anti-oxidant response element upregulation, unfolded protein response, mitochondrial biogenesis, DNA repair mechanisms, autophagy, etc.)  You say it is upregulating the AREs and I say it is upregulating autophagy.

My first line of response to this bet is that all the pathways Jim mentions are there for a reason, a very good reason —  we would soon die without any one of them.  They are all equally important for survival.  So I also declare this bet is a tie. This was also a dumb question.  

 True, I have written and thought more about the ARE’s than the other pathways.  I like them because they are so easy to upregulate using dietary substances, for example.  I also deeply respect your candidate, autophagy, as reflected in our recent blog entry Autophagy – the housekeeper in every cell that fights aging, and I quite agree that without autophagy our cells would soon die due to accumulated internal junk.  And, as declared in that blog entry “Recent discoveries have shown that almost every genetic, dietary, and pharmacologic manipulation proven to extend lifespan activates autophagy as part of its mechanism of action.”  Also, “There are many practical ways to activate Autophagy like consuming green tea and caffeine, and some less-practical ones.”  But wait a minute now, our two candidate pathways are not in fact independent.  In fact, Section 14 of the autophagy blog is devoted to “Autophagy is a key step in activating the Nrf2 pathway.  And Nrf2 expression can in turn(negatively) regulate autophagy.” And of course it is the Nrf2 pathway that activates the AREs.  So if you win the bet, I win too and if I win the bet you win too

As to your point regarding the importance of getting rid of “bad”mitochondria via autophagy:  sure I agree.  That’s essential.  But it is essential for us  to keep our mitochondria  from going bad in the first place  They are hot little beasts containing electron chain energy engines that can easily get somewhat dysregulated and start producing excess ROS.  A mechanism is essential to detect such ROS, picking it up as a signal, and activate the AREs to prevent the ROS from doing serious damage – including any damage that makes the mitochondria go bad.  Remember our blog entries Mitochondria in health and aging, and possibilities for life prolongation – Part 1:basics and Mitochondria Part 2: mitochondrial pathways, diseases and aging.  We require mechanisms both to get rid of “bad” mitochoindria and to keep them from going bad.  So I declare here too we have a tie.

As to the other stress-response pathways you mention: the UPR, the mtUPR, mitochondrial biogenesis, DNA repair mechanisms – they are all there for excellent reasons and we could not survive without any of them either.  Evolution is extremely economical and does not bother putting elaborate mechanisms in us without excellent reasons.

To allow time for the debate, the winner will be also “paid up” at end of 2013.

Of course Jim, you might want to come back with a rebuttal and seek to destroy what I have said and we can keep going on this argument.  However, at least as of now, I suggest that at the end of the year we both write each other a check for $2.00.  Also, I continue to invite readers to weigh in and take the prizes away from both of us.  Actually, I suggest that if a third party wins the wager, both Jim and I pay up our $2.00 losses making the total stakes $4.00 – doubling the stakes for that astute individual.

About Vince Giuliano

Being a follower, connoisseur, and interpreter of longevity research is my latest career, since 2007. I believe I am unique among the researchers and writers in the aging sciences community in one critical respect. That is, I personally practice the anti-aging interventions that I preach and that has kept me healthy, young, active and highly involved at my age, now 93. I am as productive as I was at age 45. I don’t know of anybody else active in that community in my age bracket. In particular, I have focused on the importance of controlling chronic inflammation for healthy aging, and have written a number of articles on that subject in this blog. In 2014, I created a dietary supplement to further this objective. In 2019, two family colleagues and I started up Synergy Bioherbals, a dietary supplement company that is now selling this product. In earlier reincarnations of my career. I was Founding Dean of a graduate school and a full University Professor at the State University of New York, a senior consultant working in a variety of fields at Arthur D. Little, Inc., Chief Scientist and C00 of Mirror Systems, a software company, and an international Internet consultant. I got off the ground with one of the earliest PhD's from Harvard in a field later to become known as computer science. Because there was no academic field of computer science at the time, to get through I had to qualify myself in hard sciences, so my studies focused heavily on quantum physics. In various ways I contributed to the Computer Revolution starting in the 1950s and the Internet Revolution starting in the late 1980s. I am now engaged in doing the same for The Longevity Revolution. I have published something like 200 books and papers as well as over 430 substantive.entries in this blog, and have enjoyed various periods of notoriety. If you do a Google search on Vincent E. Giuliano, most if not all of the entries on the first few pages that come up will be ones relating to me. I have a general writings site at and an extensive site of my art at Please note that I have recently changed my mailbox to

    Thanks to both Vince and JIm for extraordinarily interesting articles — especially the recent blog on autophagy — that’s just spectacular.

    Vince, you argue that the questions are “wrong questions” — in physics terminology. You may be right but I think most likely you are wrong. In the last year or so, we have had three spectacular life extension results in mammals: rapamycin, olive oil and olive oil spiked with buckeyballs. The extension of lifespan is so large that it seems likely that some one limiting pathway has been cleared. For example, the idea that olive oil fixes many pathways simultaneouly is possible — but by Occam’s razor should only be explored after we have eliminated the possibility of a single pathway fix.

    Maybe you should reframe the bet to: Fixing what pathway leads to the buckeyball result?

    Thanks again for your hard work, Jim Rose

    • Hey Jim Rose

      Thanks for bringing in a little controversy; it is needed. Actually I agree with you about rapamycin and olive oil. The rapamycin life-extension results are important but in fact they have been known for years.

      As to the buckyball-in-olive oil issue. I have been personally enthusiastic about it. You probably have seen my blog entry on it from November 2012 Buckyballs, health and longevity – state of knowledge at I need to take a bit of a conservative viewpoint, however, in that the spectacular 90% life extension shown in the 2012 publication (The prolongation of the lifespan of rats by repeated oral administration of [60]fullerene) was an incidental finding involving a population of only nine rats, as I recall. I gather several other groups are seeking to repeat the livespan experiments and some individuals are doing so using themselves as rats. From a hard-nosed science point of view, until confirming results of the new experiments are in, the lifespan extension observed in the original experiment are not to be fully trusted. We should know soon, however and I remain very curious.

      As to the olive oil results, a very interesting new and groundbreaking publication is (Xenohormetic and anti-aging activity of secoiridoid polyphenols present in extra virgin olive oil: a new family of gerosuppressant agents) at Check it out! The new active polyphenols in the EVOO, by the way, do activate multiple longevity pathways.

      Please keep weighing in, Jim.

      You wondered what pathway is responsible for the buckyball-in-olive oil life extension, assuming it really works.

      As pointed out in my buckyball blog entry, the most popular answer is that the mix works as a perpetually recyclable mitochondrial antioxidant, keeping down ROS damage from “old leaky mitochondrial energy engines.” Personally, I think something else fundamental is probably involved. Specifically, I think one matter to look at is the strengthening of microtubule networks, the structural elements that give cells their shapes and the “rail lines” for intra-cellular transport of cargo ranging from signaling molecules to entire mitochondria. Besides the blog entry on buckyballs, you could look at the recent Part 1 entry on mitochondria and the blog entry on microtubules at

    The buckeyball/olive oil result is truly odd. First, we apparently discover two new very robust agents:EVOO and buckeyballs. Buckeyballs are so abiological as to be ridiculous. Its as if nanodiamonds or molecular CdS gave a similar response.

    The only thing I can think of would be something like the use of piperine to increase the biological availability of curcumin. Perhaps, buckeyballs increase the permeability of the gut to some aging related component of EVOO. This might be tested by looking for other combinations of EVOO and gut irritants or other agents to increase permealizability.

    Given that we are highly optimized organisms, “How do we get a 90% increase in maximum age?” I am beginning to seriously consider a death program. What determines the maximum life span of a species? Why do the life spans of related species differ so much? Suppose that maximum life span is related to last age of fertility. There should be some particular rate of germ line genetic turnover to optimize evolution for a given species in a particular environment. Perhaps this optimum rate of germ line change make organisms have a maximum lifespan.

    On a more constructive note. Two recent papers emphasize the danger of over activating ampk. The resulting autophagy seems, on the one hand, to prune synapses and lead to Alzheimer’s and, on the other hand, overactivation seems to be related to sarcopenia.

    Cheers, Jim Rose
