US President Joe Biden turned 79 on Saturday, extending his record as the oldest person to hold the post.
Biden became the oldest president in US history in January when he was sworn in at age 78. The previous record was 77 held by Ronald Reagan when he left the White House.
Biden announced the results of a checkup on Friday. His doctor described him as a "healthy, vigorous, 78-year-old male, who is fit to successfully execute the duties of the presidency."
The president said he felt good, adding jokingly that he was looking forward to celebrating his 58th birthday.
Biden's health has been a focus of attention since he was inaugurated.
