Returned to one’s youth
To feel as one did in youth; to be reminded of one’s childhood or youth; or to return to a fit, youthful physical state.
(“Why does the verse say, ‘And Abraham and Sarah were old’? Rather, it must be interpreted that they returned to their youth; therefore it goes back and states that at the time of the announcement they were old, and then returned to their youth, as it is said: ‘And Abraham was old, advanced in days’” (Buber, Genesis 18).)
