- Franklin Delano Roosevelt (1882-1945) was the longest serving President in US History, serving three full terms and starting his fourth when he died. No other President had even won a third term (a couple had tried — Grant and T.R. — but none were elected). And, thanks to the 22nd Amendment, no President since will be able to challenge his length of service (barring the very unlikely event of the 22nd being repealed).
- Quaternary (Wikipedia)
The Quaternary (/kwəˈtɜːrnəri, ˈkwɒtərnɛri/ kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. As of 2023, the Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a third epoch, the Anthropocene, has recently been proposed, but it is not officially recognised by the ICS.
