The maximum life expectancy point is good, note that actually it's changed a bit.

"The maximum (recorded) life span for humans has increased from 103 in 1798 to 110 years in 1898, 115 years in 1990, and 122.45 years since Calment's death in 1997" - Wikipedia

And "as long as there have been people" is going way too far. Your point that there seems to be some intrinsic limit stands, until medical science disproves it.

Living forever is as ridiculous as 100% uptime, but eliminating preventable deaths remains a good goal.
