As he celebrates his 81st birthday on Monday, US President Joe Biden knows very well that his age is also his main handicap in the lead-up to the 2024 presidential election. During a speech to workers in the automotive industry, he mocked concerns about his physical fitness and mental sharpness, joking that it was not him who had fallen during the event. Democrat Biden is already the oldest president in American history and will be 86 years old if he wins a second term. According to his last systematic examination in February, Biden is in good health, but voting for him means taking a risk on whether it will remain that way until the end of a possible second mandate. Recent polls have shown that Americans are not excited about this bet, with 71% saying that Biden is too old to be president. However, polls also show that former president Donald Trump, who is also 77 and not considered “chicken,” faces similar questions about his mental abilities. The former chief strategist of the Democrats, David Axelrod, has advised Biden to question whether he is running for personal or national interest based on these findings. Stuart Jay Olshansky, who studies longevity at the University of Illinois, believes that aging is not what it used to be and encourages people to focus on their overall health rather than just their age. Before the 2020 election, Joe Biden cut back on travel due to the pandemic but will now have to travel across America as he takes on more responsibilities as president. Although his doctor describes him as “strong,” there is no doubt that Biden’s appearance corresponds to his age – his gait is very stiff, his voice is often weak and difficult to hear, and his speech slurred. Biden now enters Air Force One via a shorter staircase instead of the larger stairs used before because they were too unstable for him to pose near the top without falling again. Despite these challenges and concerns about his age, Biden regularly claims that it guarantees “wisdom” on matters of American political life and turmoil in the world.
