Exceedingly long life spans
Retirement plans were expensive in the early days
THE BOOK OF GENESIS
The Book of Genesis is chock-full of centenarians. Adam was 130 years old when he had a son named he Seth. Adam lived a total of 930 years before he died, while his son Seth was 105 years old when he fathered Enosh, ultimately living to the age of 912. Enosh then lived for 905 years. Scholars have long debated why the Book of Genesis tells of people having super-long lifespans. One possibility is that the writers of Genesis measured the length of a year differently, while another possible explanation is that the shortening lifespans as the Bible goes on is a punishment for humanity's sins.
