George Washington was 43 when the Continental Congress placed him in command of the fledgling army that would eventually drive the British out of their American colonies. At 55, the general presided over the fractious convention that produced the most durable constitution the world has ever seen.

If our four best presidents entered office at an average age of 50, why am I reading about potential candidates for 2020 who will be in their 70s? Former vice president Joe Biden says he is thinking about making a run. If he won, he would take office at 78. Sen. Bernie Sanders (I-Vt.) has been touted as a front-runner for the Democratic nomination. He would be 79. Sen. Elizabeth Warren (D-Mass.) beams as throngs of Democrats chant her name. If she runs and wins, she would take the oath at 71.
Until Donald Trump came along, the United States had never sent a septuagenarian to occupy the Oval Office. (We did keep one there in 1984, when Ronald Reagan was reelected at 73.) We’ve sworn in more than twice as many presidents under the age of 50 as over the age of 65. That serious people are discussing candidates who would be pushing 80 is unprecedented — and sclerotic for our political system.
My point is not to disparage the elderly, for I am rapidly becoming one myself. But no thriving society finds its fresh thinking among its oldest leaders. The wisdom of years is a check, not an engine. Though age takes its toll in different ways on different people, in the aggregate the science is clear: Mental agility, executive function and creativity all tend to decline as we pass through middle age.

Older adults tend to be slower in conceptualizing and less ready to change strategies when circumstances shift.”
