How old is too old? Former vice-president Joe Biden is 76 years old and Senator Bernie Sanders is 77. Two years from now, would either man be too old to be president of the United States? Not just physically, but also culturally and temperamentally?
Mr Donald Trump, though he was the oldest person (at 70) to be elected president, doesn't seem to have a problem with age, not so much because of his full head of dyed hair, but because he is strangely ageless.
