Roughly the same as it's ever been. Ancient Kings and Pharaohs lived to their 70's and there were probably old fucks in the countryside living to their 90's that you never heard about. You can safely consider 100 to be about where the asymptote is, besides a few outliers (many of which have been called into question due to the unreliability of birth records from that long ago).
>end of the centuryOn second thought, "average" life expectancy in every country is probably going to be back down to around 30 by then as there will be no civilization for neonatal care so infant mortality will skyrocket. As is natural for the human species.
>>14184352What I've noticed is that once a person reaches a certain point in their life, their bodies become as delicate as glass. Usually this happens about 80 or 90, though very rarely (usually genetics) around 100. But once this point is reached, the slightest thing will cause total system collapse and death. A fall. A respiratory illness. Death of their spouse. A minor infection. A small stroke. A broken bone. After the event, they quickly enter a steep decline. Sometimes they die in a few days; sometimes they linger for months or even years, basically bedridden and paralyzed. But they never come back.
I've also noticed that medications can extend the period before that point by 10-20 years. A person who was genetically likely to reach it by 70 can make it to 80, on an increasingly absurd cocktail of pills the take three times per day. But it never changes what happens after that point. All "modern medicine" can do when a body is ready to die, and suffers a setback from which it cannot return, is to preserve it in a zombie state. Shove tubes and wires into it and keep it alive by machines and outside maintenance.
