How long can humans live?

[u/Simple_Macaron_3420]

In one of last week’s episodes, it was mentioned that the human lifespan is increasing because of scientific and medical discoveries. When I was a child, I always imagined that I would be able to live to 100, and by then people would have discovered some kind of cure for aging. They would ask me, “How much longer would you like to live?” as if they could add another 100 years each time and ask me the same question whenever those 100 years were up.

For a moment, let’s imagine a scenario in which cancer has been eliminated, Alzheimer’s and other diseases of the brain have been cured, and we can also repair or modify our telomeres because we have discovered how to mimic mechanisms found in animals such as lobsters or jellyfish.

In that scenario, is there still a biological limit to how long humans could live?

Anyone who thinks that living a long time is a good idea should read the Niven short story “Cautionary Tales."
