I only know the age of one of them, and she was... 80 something and still alive when I was born those 21 years ago. Not sure about the others.Specter_ said:Judging from you age, your great-grandparents shouldn't have lived long enough to develop cancer. During the early 20th century, life expectancy was 30-40 years, so the chances to develop cancer (as it's main cause is simply age) were slim to none.Inverse Skies said:(I'm not sure about great-grand parents, but even then I don't think so)
Uhhh... where are you getting your data for lifespan from? Because I've just pulled up an old lecture slide which says the median lifespan for a US citizen in 1900 was 61 years.
