I am interested in finding ways and coming up with ideas to help extend the human lifespan. As I've wondered why is 118 such a hard age to reach? Do most human organs have a lifespan of 117 years, and there was something extra special about Randon, Knauss, Tanaka, and Calment? Is there way we can help more SCs make it to 118 and higher? What was different about the 4 people that indeed did make it to 118 and above? Are most people born with organs that will last for 125 years or more, but their lives are shortened by unhealthy lifestyle choices, poor diet, and other factors? If some theoretical person were to be born with the absolute best possible human organs, had an extremely healthy lifestyle, and excellent luck, how long would such a person live? Would they only narrowly outlive Calment by a few months and reach 123, or would they live much longer? Like 126? Or even 130? Did Calment actually reach the limit of human lifespan without medical or technological intervention? Going by the statistics for one 122 year old we would need two 121 year olds, four 120 year olds, eight 119 year olds, sixteen 118 year olds, and thirty-two 117 year olds, so obviously Calment was extremely lucky. 

I find longevity really intriguing and interesting but I don't know who else to ask these questions, and I have absolutely zero knowledge on Biology. Any answers on these questions wold be extremely helpful to me! Thank you!

I suspect that age 118 should become easier for women to reach over time. Perhaps comparable to age 117 or even (long-term) 116 today.

As you’ll know, a fairly common cause of death for S/C’s id multiple organ failure or similar, essentially where one (say 114 year old) organ  begins to fail and others go down as well, because they are not up to the additional work and stress of carrying the one that may be dying.

As you suggest how much longer may each have lasted without that additional stress?

The other problem of course is that transplanted organs often do not last long in their new home, and with our current scientific expertise it’s logically unforeseeable that the remaining organs (in my hypothetical 114 year old) would go to another human.

For body parts, it's less deadly for extremely old people if a non-vital body part such as the eyes or ears give out. It makes them blind or deaf but allows them to continue living, sometimes for several additional years, as with Lucile Randon. But if a vital body part gives out, then it can rapidly become over for extremely old people, tragically and unfortunately.

First of all, I'd like to say I'm pretty sure that Christian Mortensen was the longest title holder of oldest living man in the United States and Sarah Knauss was the longest title holder of oldest living woman in the United States. How rare is it, that they lived at exactly the same time in history? Both born in the 1880s and died in the 1990s.

And I know this might sound like a dumb question, but why do tortoises have the potential to live to be 190 years old, possibly older, while a human has only reached 122? I don't know if it's possible, but maybe humans can learn something from this? Obviously a Tortoise's DNA ages slower, maybe we could develop some kind of technology that protects our DNA? I really don't know, I'm not a scientist lol

US-born white men really did have a golden age of longevity for the 1880s and 1890 birth years. Frederick Frazier, Walter Richardson, Donald Butler, John McMorran, and Fred Hale. Afterwards we had Walter Breuning but no one else as impressive among US-born white men (or any other US-born men for that matter, though the US-born black men did do better than the US-born white men did for those born after 1890, with the exception of Mr. Breuning).

I don't know why I mentioned Donald Butler above here. He was black, not white. The other four men here were white, though. One could also mention John Painter, who died at almost age 112.5 and who was born in late 1888.

What's the comparable figure for males? One male in two million? I want to know just how many future verifiable male SCs we got deprived of due to the World Wars, for instance.
