Let's look at the Biden Presidency through his age. (Yes I know Trump is only about 4 yrs younger, but obviously has mental acuity to be pres.)
1. Biden is so old that FOUR Presidents were of a younger generation (Boomers- Clinton, Bush, Obama, Trump) BEFORE Biden (Silent Generation) became President!
2. Biden was born closer to Abraham Lincoln's Presidency, THAN HIS OWN!
Lincoln's presidency ended with his death from assassination on April 15, 1865. Biden was born on November 20, 1942, and inaugurated on January 20, 2021. The gap between Lincoln's death and Biden's birth is roughly 77.6 years, The time between Biden's birth and being sworn in as president is 78.2 years.
3. The median age of US citizens is about 38 yrs. Biden is more than DOUBLE that age.
