People in the past were not all dead by 30. Ancient documents confirm this. In the 24th century BCE, the Egyptian Vizier Ptahhotep wrote verses about the disintegrations of old age. The ancient Greeks classed old age among the divine curses, and their tombstones attest to survival well past 80 years. Ancient artworks and figurines also depict elderly people: stooped, flabby, wrinkled.
This is not the only type of evidence, however. Studies on extant traditional people who live far away from modern medicines and markets, such as Tanzania's Hadza or Brazil's Xilixana Yanomami, have demonstrated that the most likely age at death is far higher than most people assume: it's about 70 years old. One study found that although there are differences in rates of death in various populations and periods, especially with regards to violence, there is a remarkable similarity between the mortality profiles of various traditional peoples.
High infant mortality and inaccuracy at the other end of the age range skew the numbers.

I figured lots of babies died before they turned 3, but if they made it to 3 they were good for another 70 years.
Then again I took a college statistics class (um, no I didn't. Realized it was important long after I graduated and taught myself. Wasted my time on women's studies and the psychology of old Science Fiction movies instead).
SDSU for the lose! They cancelled my statistics and technical writing classes, ended up taking the aforesaid women's studies and psychology of old SciFi movies classes instead. Which makes me well rounded, or something.
/ Whatever, 10 years after graduation I was well rounded.
// Women's studies. Forced my way in as I was gonna graduate and needed a GenEd class
/// Teacher flat out said if she had her way no males would be in her class
//// Pissed the class off multiple times. Ignore assignments, study 10 minutes before the test, get an A.
///// Psychology of SciFi movies?
////// Interesting as hell, surprising enough, but useless.
/////// A class in basic statistics, or technical writing?
//////// Would have been much more useful
/ I should spend less time on fark
