The presidency of the US is anchored by an economy, consequential world affairs, and the need to remain in touch with millions of people.

President Joe Biden, who represented Delaware in the Senate for 36 years before serving as vice president for eight, knows the complexity of the office due to his years of lawmaking in the White House.

According to The New York Times, several White House aides keep an eye on the commander-in-chief, aware that he is aware of official affairs, but still keeping his energy up.

While impressive for a man of his age, his energy level is not what it was and some aides watch out for him.

Some of Biden's aides were concerned that he could potentially fall while walking. It was noted that some aides hold their breath when the president is speaking, hoping that he won't make a mistake.

He would be 86 at the end of his second term if Biden were to be reelected in 2024.

In recent months, some Democratic voters have expressed concerns with Biden's age, with more than a few pointing to his more moderate and congenial brand of politics, which has fallen out of favor among the most fervent partisans who have been elected to congress in recent years.

Biden has said that he will run for president in 2024, which could lead to a second election against Trump.
