If you live (or reign) long enough, you get to set many records.
Queen Elizabeth II was born in 1926 and became monarch in 1952.
She has seen many US Presidents:
LB Johnson (1963-69)
Bush Sr (1989-93)
Bush Jr (2001-09)
Or, every Indian PM from Nehru onward. And every Indian president since Prasad.
She also outlived Emperor Hirohito who ruled since 1926 (when she was born!) up to 1989. Fidel Castro and Robert Mugabe made determined efforts to outlast her, but did not succeed.
And a long list of UK Prime Ministers:
Douglas-Home (1963-64); (arguably the most obscure of these PMs, but often figures in trivia quizzes as he is the only British PM to play first-class cricket. A puny record compared to that of Imran Khan, but he achieved more than Nawaz Sharif in his 1-match career).
Want to bet that the Queen will still be around after Trump and Johnson depart?
Tail piece: Britain now has a PM with Russian as well as French traces in his name:
Alexander Boris de Pfeffel Johnson
Also born in New York City in 1964, like Trump (1946).
He is older than one of his predecessors (Cameron) who was born in 1966.
