Hall of Fame
yeah, Agassi was pretty well broken physically well before 40, so he probably has no idea how it’s possible. His experience was different. That last year he could barely walk.Many years ago Agassi used the "he's writing checks that his body can't cash" phrase about Nadal.
He's clueless on the subject of longevity.....pure guesswork.
And its definitely possible to win a major at age 40, that I can tell you.
