Backing away from the "rubbishing superstition" mode in case of yellow cards
Interesting factoid on height of modern man, a topic being discussed earlier in the thread - one I came across a decade or so, but didn't believe until I checked the facts out.
The height of the average Japanese male increased by over 6 inches in the first generation following WW2. Apparently this was purely down to the increase in the amount of protein in the diet following the American occupation. Yes, Big Macs are good for you! And apparently studies done on sailors' bones around the time of the Mary Rose showed similar height averages to the previous generation of Brits - the current generation is significantly taller (as anyone who has had teenage kids will confirm!)
