“I think this is a valid question that is acceptable to ask anyone over 70 if they are healthy and ready, it is a valid question, but I can only tell Americans: you will see,” Biden told ABC.

He confirmed that he is ready to serve as president for eight years.

As the TV channel clarifies, if he wins the elections at the time of his inauguration, Biden will be 78 years old.

On August 21, Joe Biden formally confirmed his agreement to run for president of the United States from the Democratic Party in the upcoming presidential elections.

American President Donald Trump called the candidates' almost equal chances of winning the US elections.
