I'd be interested to know how advanced Daniel's perspective is, what his "beliefs" are, etc.
Being a human calculator is somewhat impressive, but I'm not sure it necessarily translates into rationality (however we choose to define the term).
Don, you possibly already saw this, but here's
a sketch.

"Will Humans Soon Live 1,000 Years? The Answer is No."
There have been a flurry of news reports in the past few days about the possibility that one day soon humans will be capable of living up to 1,000 years.
It's certainly true that the average life expectancy has risen dramatically in the past 100 years: in 1901 life expectancy for newborn babies was 45 for boys and 49 for girls. By 2000 life expectancy was 75 and 80 respectively.
However much of this improvement has come from large reductions in infant mortality due to better living conditions and access to medicine, and not because of any fundamental change in how humans age. There are in fact many reliable reports of long life spans throughout history: Plato (80 years), Augustus (76 years), Pope Celestine III (91 years), Isaac Newton (84 years). The ancient Greek philosopher Democritus of Abdera is reputed to have lived to the age of 109.
Indeed the maximum life span for humans has not really changed throughout human history; remaining around 115-120 years. The oldest-ever person was a French woman, Jeanne Calment, who lived 122.5 years (1875-1997).
It seems that with a healthy diet and regular exercise most people in the developed world today can expect to live somewhere between 70-90 years, with a small number living to or past 100 years. But claims of massively increased life spans in the near future are no more than pure speculation.
And, anyway, isn't quality of life more important than quantity?

[A comment of his under his post.]
There are too many comments to respond to them here individually, but let me attempt a few thoughts:
1. I have read Aubrey de Grey's ideas and disagree with them.
2. I'm not in the least afraid of the idea of people living very long lifespans. I just don't think it is going to happen.
3. Aging isn't a disease like depression or cancer, but an extremely complex process. I doubt whether it would ever be possible to stop it as is claimed.
4. I have no problem with research into aging - especially where the focus is on maintaining good all-round health throughout the natural lifespan.
5. Of course quantity can affect quality - the entire essence of things like art or literature or music or poetry is working within limitations. The problem with obsessing over quantity is that it negates the possibility of a full and rich life being lived in a few or few dozen years.
6. Some people achieve an enormous amount in twenty years, while others achieve little in over one hundred. Simply extending lifespan won't necessarily make us any smarter, enlightened, happier.
7. The desire for a very long lifespan is understandable and perhaps even admirable. But we have to look at it from a perspective outside of itself (as with all things). Even if something became possible that wouldn't necessarily mean we ought to do it.
Possibly more can be analyzed. I'll start by inserting this.
In response to 5., where he used "limitations," he might've instead used "constraints." They both can produce the same products of art, but the meaning of constraints recognizes that 'to be appropriately disciplined', also part of the meaning of limitations, doesn't further mean 'to have an upper bound', unlike in the intended meaning of limitations.
In response to 6., if we can live extremely extended lives, there will be some who want to take their time and smell the roses, and there will be some who want to be super-achievers, and the reasoning of either could virtually never be convincingly disputed.
In response to 7., if working out Sudoku puzzles all day every day is doable, that wouldn't necessarily mean we ought to do it.
