Joe Biden, 80, is the oldest U.S. president to ever serve in the White House, and nearly two decades older than the median age of the world's national leaders, 62, Pew Research found.
Republican Senator Chuck Grassley of Iowa, 89, Democratic Senator Dianne Feinstein of California, 89, and Vermont Senator Bernie Sanders, 81, are older than McConnell.
Many congressional lawmakers are in their 70s, and the median age of the Senate is 65.3, FiveThirtyEight calculated, the oldest ever, versus a median age of 38.8 years in the United States as a whole.

Biden doesn't make the top 10 of the world's oldest currently serving leaders, according to Pew, which in addition to Biya is led by Mahmoud Abbas, president of the Palestinian Authority, at age 87.
