"Let's set an age limit after which you can't run for political office, perhaps a number just below 70," Musk posted on Twitter.
Last month, the billionaire commented on Independent Vermont Sen. Bernie Sanders's wealth-tax offer, saying he kept forgetting Sanders was "still alive." Sanders is 80, far above the proposed age limit by Musk.
Other politicians affected by Musk's offer are veteran Sens. Dianne Feinstein, D-Calif., who turned 88 in June, and Charles Grassley, R-Iowa, 88. President Biden, 78, was the oldest president to take office, and former President Trump is now 75.

Supreme Court Chief Justice John Roberts wrote about imposing age limits in a 1983 memo as an assistant to White House counsel under President Ronald Reagan, according to the USA Today.
"Setting a term of, say, 15 years would ensure that federal judges would not lose all touch with reality through decades of ivory tower existence," Roberts wrote. "It would also provide a more regular and greater degree of turnover among the judges."

"We should have an expectation about Congress," Barro wrote in The New York Times, "that people will retire when they are no longer up to the demands. One way to achieve this would be through formal rules. Senators in Canada must retire at the age of 75, and many state court systems also have mandatory retirement ages."
