300 year old average life expectancy? There'd be no one alive in 1923 who could reach 300 by 2023, much less enough for it to be an average.

That's not how life expectancy works. If the life expectancy for 2023 would be 300, it means people born in 2023 would live to 300 on average.

No, life expectancy is calculated based on the average age at death in that year.

Life expectancy is the number of years that someone is expected to live from a specific starting point. Typically birth. So, yes, people in 1923 could expect life expectancy for people being born in 2023 to be 300 years.

Yeah, I do realize how life expectancy works, but there would be no way to get from where we were to 300 in just a century unless a true fountain of youth was found. Life expectancy uses historical data.

They're saying modern medicines of 2023 would mean that someone born on 2023 would have a life expectancy of 300 years

I get that, but I still don't believe there'd be a way to get to 300 to where we knew and could predict that at birth for 2023.
