he is 87 years old
each year has 365 days (I know some years have 366 days, just i case @Rollout thinks I don't know this)
so 87x365=31,025 days
Assuming he started landing on day 1 and that he still lands, that makes it more than one airport a day!! marvelous!!
When I have money, I get rid of it quickly, lest it find a way into my heart.
