US President Joe Biden officially announced his 2024 election campaign, running for a new term. Biden is the oldest president in the history of America, and faces many challenges, most notably his health.

Biden's approval rating remained at just 39 percent in a Reuters/Ipsos poll on April 19, and some Americans are deeply concerned about his age. If he wins, he will turn 86 at the end of his potential second term, about a decade more than the average age of men in America.
