Nature vs Nurture

I just read an interesting news on BBC online about Bolivian football players being prescribed doses of Viagra to help them play better on high altitude. Viagra, as we know, helps to expand blood vessels and oxygenate the blood, thus providing more stamina and endurance to its users.

This brings up the question whether the recent Bolivia's 6-1 thrashing of Argentina was due to the Bolivian players inherent ability to play at high altitude or was Viagra the secret weapon that gave them the added advantage and propelled them into a resounding victory?

It's hard to say unless if the Argentinian team also used Viagra to help boost its chance of winning in La Paz. But if I have to make an educated guess, I'd say that it was the Bolivian players' unique biological structure i.e. "Nature" that made them play well on their native high grounds. I made this assumption based on two reasons: Not all humans are created equal and we are physically and mentally shaped by the environment we grew up in, and it is known that natives of high altitude have bigger-than-normal blood vessels and more expansive lung capacity to help them adapt to their surroundings; second, I doubt that South American teams with a long horrendous track record at La Paz are ignorant of ways - scientific or otherwise - to increase blood flows to the heart and brain that would help level the playing field, literally and figuratively speaking.

Argentinian and Brazilian team doctors and physiotherapists are not stupid and I'm almost certain they know the benefits of using Viagra in high-altitude matches. Why they almost never won in La Paz can then be chalked up to the Bolivian players' natural ability to play in thin-air environment. If, say, Malaysian national footballers are forced to play Zenit St. Petersburgh in the bone-freezing, snow-covered field of Russia, I'm sure they'll lose by 20 goals or more. What if the table is turned and Zenit has to play in hot and muggy Malaysia? I'm sure as heck it'll still win, but only by 10 goals or maybe less... Yeah, this goes to show how patriotic I am!
