A comment on No limit to maximal lifespan in humans: how to beat a 122-year-old record. Parent comment
There is no hard limit, but clearly the age distribution drops suddenly (for developed countries) at 70.
There are a bunch of single points of failure in our body -- the heart, the liver, the spine, the major blood vessels, the trachea, etc.
There's only so many 9's that those components are built to last for, and they ALL have to work!
FYI: I agree that "Leading demographers ... 122 years" is an incorrect statement.
