And for me, it's quite romantic, but it's about if one person teaches three people how to cook something, and they teach three of their mates, that only has to repeat itself 25 times, and that's the whole population of America.
Ale stačí, aby jeden člověk naučil další tři jak něco uvařit, a oni zase každý naučí tři kamarády, a stačí to opakovat jenom 25 krát, a máme pokrytou veškerou populaci Ameriky.
