As an non native english speaker i read:

> How tall was the president when JFK was born?

as, How tall was the "reigning" president, (which in the year 1917, Kennedys birth year, was Thomas Woodrow Wilson) on the day that JFK was born."

Let's talk about Biden, then. How tall was the president when he was born?
