Keeping up with John Paul II

"John Paul set a pace of physical activity during the first fourteen years of his pontificate that often left those around him gasping in the dust. (He could, and did, tease others about their stamina, or lack thereof. When the papal plane crossed the international date line on its circumnavigation of the globe, during a grueling two-week pilgrimage to the Philippines, Guam, Japan, and Alaska in February 1981, the Pope, mischief in his eyes, cracked to an exhaustsed papal entourage and press corps, "Now we must decide what tod o with the extra day we've been given.")
