Prince Philip celebrates his 95th birthday this year, but he is still putting the younger generation of royals to shame.
The Daily Mail reported the Queen's husband undertook 217 official engagements in the UK last year - more than Prince William, the Duchess of Cambridge and Prince Harry combined, who together clocked up just 198 between them at home.
However, online commenters have pointed out Harry was in the army, William was working as a rescue helicopter pilot and Kate was ill with morning sickness and on maternity leave for much of the year.
With visits to Malta and Germany, the Duke of Edinburgh undertook a staggering 250 official engagements. The 89-year-old Queen, who became the longest reigning monarch in British history, undertook 341 engagements - 306 in the UK and 35 abroad.
The busiest member of the royal family was Princess Anne, who pipped her brother, Prince Charles, to the top spot for the first time in eight years. She had 456 engagements at home and 88 overseas.
