The participants who lived long, happy lives "were not cynical rebels and loners" but accomplished people who were satisfied with their lives. Many knew that worrying is sometimes a good thing. The authors also looked at a study of Medicare patients that found that "neuroticism was health-protective."

spending 30 minutes at least four times a week expending energy at a moderate to intense level is "good up-to-date medical advice but poor practical advice."

Being active in middle age was most important to health and longevity in the study. But rather than vow to do something to get in shape (like jogging) and then hate it and not stick with it, find something you like to do."We looked at those who stayed active," Friedman says. "It wasn't the kids on sports teams. It's the ones who had activities at one point and had the pattern of keeping them ... They were doing stuff that got them out of the chair ... whether it was gardening, walking the dog or going to museums."

One of the best childhood personality predictors of longevity was conscientiousness — "qualities of a prudent, persistent, well-organized person, like a scientist or professor — somewhat obsessive and not at all carefree,"

the most obvious reason "is that conscientious people do more things to protect their health and engage in fewer activities that are risky."

"What characterized the people who thrived is a combination of their own persistence and dependability and the help of other people," Friedman says. The young adults who were thrifty, persistent, detail-oriented and responsible lived the longest.

Those with the most career success were the least likely to die young. Those who moved from job to job without a clear progression were less likely to have long lives than those with increasing responsibilities.

"continually productive men and women lived much longer than the laid-back comrades. ... This production orientation mattered more than their social relationships or their sense of happiness or well-being."

those who were most engaged in pursuing their goals.

a sexually satisfying and happy marriage is a very good indicator of future health and long life," but being single for a woman can be just as healthy as being in a marriage, especially if she has other fulfilling social relationships.

The married men in the study lived the longest. Single men outlived remarried men but didn't live as long as married men. Among women, the number who divorced their husbands and stayed single lived nearly as long as steadily married women."Being divorced was much less harmful to a women's health," the authors say.

Agar directly tackles Hughes’ ideas of a “democratic transhumanism.” Here as post-humans and humans live shoulder to shoulder in wonderful harmony, all persons have access to the technologies they want in order to promote their own flourishing.  Under girding all of this is the belief that no human should feel pressurised to become enhance. Agar finds no comfort with this and instead can foresee a situation where it would be very difficult for humans to ‘choose’ to remain human.  The pressure to radically enhance would be considerable given the fact that the radically enhanced would no doubt be occupying the positions of power in society and would consider the moral obligation to utilise to the full enhancement techniques as being a moral imperative for the good of society.  For those who were able to withstand then a new underclass would no doubt emerge between the enhanced and the un-enhanced. This is precisely the kind of society which Hughes appears to be overly optimistic will not emerge but which is more akin to Lee Silver’s prediction of the future with the distinction made between the "GenRich" and the "naturals”.  This being the case, the author proposes that we have two options: radical enhancement is either enforced across the board or banned outright. It is the latter option which Agar favours but crucially does not elaborate further on so it is unclear as to how he would attempt such a ban given the complexity of the issue. This is disappointing as any general initial reflections which the author felt able to offer would have added to the discussion and added further strength to his line of argument.

A Transhuman Manifesto The final focus for Agar is James Hughes, who published his transhumanist manifesto Citizen Cyborg in 2004. Given the direct connection with politics and public policy this for me was a particularly interesting read. The basic premise to Hughes argument is that once humans and post humans recognise each other as citizens then this will mark the point at which they will be able to get along with each other.

Agar takes to task the argument Bostrom made with Toby Ord, concerning claims against enhancement. Bostrom and Ord argue that it boils down to a preference for the status quo; current human intellects and life spans are preferred and deemed best because they are what we have now and what we are familiar with (p. 134).  Agar discusses the fact that in his view, Bostrom falls into a focalism – focusing on and magnifying the positives whilst ignoring the negative implications.  Moreover, Agar goes onto develop and reiterate his earlier point that the sort of radical enhancements Bostrom et al enthusiastically support and promote take us beyond what is human so they are no longer human. It therefore cannot be said to be human enhancement given the fact that the traits or capacities that such enhancement afford us would be in many respects superior to ours, but they would not be ours.

With his law of accelerating returns and talk of the Singularity Ray Kurzweil proposes that we are speeding towards a time when our outdated systems of neurons and synapses will be traded for far more efficient electronic circuits, allowing us to become artificially super-intelligent and transferring our minds from brains into machines.

Having laid out the main ideas and thinking behind Kurzweil’s proposals, Agar makes the perceptive comment that despite the apparent appeal of greater processing power it would nevertheless be no longer human. Introducing chips to the human body and linking into the human nervous system to computers as per Ray Kurzweil’s proposals will prove interesting but it goes beyond merely creating a copy of us in order to that future replication and uploading can take place. Rather it will constitute something more akin to an upgrade. Electrochemical signals that the brain use to achieve thought travel at 100 metres per second. This is impressive but contrast this with the electrical signals in a computer which travel at 300 million metres per second then the distinction is clear. If the predictions are true how will such radically enhanced and empowered beings live not only the unenhanced but also what will there quality of life really be? In response, Agar favours something what he calls “rational biological conservatism” (pg. 57) where we set limits on how intelligent we can become in light of the fact that it will never be rational to us for human beings to completely upload their minds onto computers.

Agar then proceeds to argue that in the pursuit of Kurzweil enhanced capacities and capabilities we might accidentally undermine capacities of equal value. This line of argument would find much sympathy from those who consider human organisms in “ecological” terms, representing a profound interconnectedness which when interfered with presents a series of unknown and unexpected consequences. In other words, our specifies-specific form of intelligence may well be linked to species-specific form of desire. Thus, if we start building upon and enhancing our capacity to protect and promote deeply held convictions and beliefs then due to the interconnectedness, it may well affect and remove our desire to perform such activities (page 70). Agar’s subsequent discussion and reference to the work of Jerry Foder, philosopher and cognitive scientist is particularly helpful in terms of the functioning of the mind by modules and the implications of human-friendly AI verses human-unfriendly AI.

In terms of the author’s discussion of Aubrey de Grey, what is refreshing to read from the outset is the author’s clear grasp of Aubrey’s ideas and motivation. Some make the mistake of thinking he is the man who wants to live forever, when in actual fact this is not the case.  De Grey wants to reverse the ageing process - Strategies for Engineered Negligible Senescence (SENS) so that people are living longer and healthier lives. Establishing this clear distinction affords the author the opportunity to offer more grounded critiques of de Grey’s than some of his other critics. The author makes plain that de Grey’s immediate goal is to achieve longevity escape velocity (LEV), where anti-ageing therapies add years to life expectancy faster than age consumes them.

In weighing up the benefits of living significantly longer lives, Agar posits a compelling argument that I had not fully seen before. In terms of risk, those radically enhanced to live longer may actually be the most risk adverse and fearful people to live. Taking the example of driving a car, a forty year-old senescing human being who gets into their car to drive to work and is involved in a fatal accident “stands to lose, at most, a few healthy, youthful years and a slightly larger number of years with reduced quality” (p.116). In stark contrast should a negligibly senescent being who drives a car and is involved in an accident resulting in their death, stands to lose on average one thousand, healthy, youthful years (p.116).  

De Grey’s response to this seems a little flippant; with the end of ageing comes an increased sense of risk-aversion so the desire for risky activity such as driving will no longer be prevalent. Moreover, plus because we are living for longer we will not be in such a hurry to get to places!  Virtual reality comes into its own at this point as a means by which the negligibly senescent being ‘adrenaline junkie’ can be engaged with activities but without the associated risks. But surely the risk is part of the reason why they would want to engage in snow boarding, bungee jumping et al in the first place. De Grey’s strategy seemingly fails to appreciate the extent to which human beings want “direct” contact with the “real” world.

Continuing this idea further though, Agar’s subsequent discussion of the role of fire-fighters is an interesting one.  A negligibly senescent fire fighter may stand to loose more when they are trapped in a burning inferno but being negligibly senescent means that they are better fire-fighters by virtue of increase vitality. Having recently heard de Grey speak and had the privilege of discussing his ideas further with him, Agar’s discussion of De Grey were a particular highlight of the book and made for an engaging discussion. Whilst expressing concern and doubt in relation to De Grey’s ideas, Agar is nevertheless quick and gracious enough to acknowledge that if such therapies could be achieved then De Grey is probably the best person to comment on and achieve such therapies given the depth of knowledge and understanding that he has built up in this area.

Ptolemy’s portrayal of Kurzweil is unmistakably positive, but to his credit he includes several critics from both religion and science. From the former, a radio host named Chuck Missler, a born-again Christian who heads the Koinonia Institute (“dedicated to training and equipping the serious Christian to sojourn in today’s world”), proclaims: “We have a scenario laid out that the world is heading for an Armageddon and you and I are going to be the generation that’s alive that is going to see all this unfold.” He seems to be saying that Kurzweil is right about the second coming, but wrong about what it is that is coming. (Of course, Missler’s prognostication is the N+1 failed prophecy that began with Jesus himself, who told his followers (Mark 9:1): “Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.”) Another religiously-based admonition comes from the Stanford University neuroscientist William Huribut, who self-identifies as a “practicing Christian” who believes in immortality, but not in the way Kurzweil envisions it. “Death is conquered spiritually,” he pronounced.

On the science side of the ledger, Neil Gershenfeld, director of the Center for Bits and Atoms at the Massachusetts Institute of Technology, sagely notes: “What Ray does consistently is to take a whole bunch of steps that everybody agrees on and take principles for extrapolating that everybody agrees on and show they lead to things that nobody agrees on.” Likewise, the estimable futurist Kevin Kelly, whose 2010 book What Technology Wants paints a much more realistic portrait of what our futures may (or may not) hold

Kelly agrees that Kurzweil’s exponential growth curves are accurate but that the conclusions and especially the inspiration drawn from them are not. “He seems to have no doubts about it and in this sense I think he is a prophetic type figure who is completely sure and nothing can waiver his absolute certainty about this. So I would say he is a modern day prophet…that’s wrong.”

Transcendent Man is clearly meant to be an uplifting film celebrating all the ways science and technology have and are going to enrich our lives.

An especially lachrymose moment is when Kurzweil is rifling through his father’s journals and documents in a storage room dedicated to preserving his memory until the day that all this “data” (including Ray’s own fading memories) can be reconfigured into an A.I. simulacrum so that father and son can be reunited.

Although Kurzweil says he is optimistic and cheery about life, he can’t seem to stop talking about death: “It’s such a profoundly sad, lonely feeling that I really can’t bear it,” he admits. “So I go back to thinking about how I’m not going to die.” One wonders how much of life he is missing by over thinking death, or how burdensome it must surely be to imbibe over 200 supplement tables a day and have your blood tested and cleansed every couple of months, all in an effort to reprogram the body’s biochemistry.

This “technophysio evolution,” powered by advances in food production and public health, has so outpaced traditional evolution, the authors argue, that people today stand apart not just from every other species, but from all previous generations of Homo sapiens as well.

 “I don’t know that there is a bigger story in human history than the improvements in health, which include height, weight, disability and longevity,” said Samuel H. Preston, one of the world’s leading demographers and a sociologist at the University of Pennsylvania. Without the 20th century’s improvements in nutrition, sanitation and medicine, only half of the current American population would be alive today, he said.
