I too have friends in this category. I know really tall guys who are solid muscle and weigh a LOT. They're not fat at all but they are approaching the weight of two average people, easy.

What really astounds me, though, are skinny girls going away for three days but check-in TONS of luggage. It also is invariably over the weight limit and they end up paying excess.

Guys, on the other hand, take a tiny little rucksack on as hand luggage containing a clean shirt, a clean pair of kecks and their toothbrush for the same trip. It also means NO WAITING for luggage at the other end.
