Lifespans of 1800s presidents compared to today's presidents

[Plankton5165]

Presidents in the late 1800s and early 1900s tended to live shorter lives than presidents that have already died in the 21st century.

As an example, Gerald Ford died in 2006 at age 93 and George H. W. Bush in 2018 at 94. Jimmy Carter is even still alive at 99!

If you think death is never easy, and 70 is a young age at death, two more examples: Franklin Pierce, born in 1804, died in 1869 at age 64; Calvin Coolidge lived from July 4, 1972 to January 5, 1933, he died abruptly at age the age 60. Pretty much the same goes for every other president between numbers 9 and 30; not only are they long gone, but only one of which lived past their 75th birthday: Buchanan. Only three POTUSes 16 to 30 made it to their 70s, and even all three of those died younger than James Monroe, the shortest lived of presidents 2 to 8!

Why is that? At their time, even the PMs of the United Kingdom tended to live long lives! Like William Gladstone, who lived from 1809 to 1898.
