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.
Bet tiesiog jei vienas žmogus išmoko tris žmones, kaip kažką pagaminti, ir jie išmoko tris kitus savo pažįstamus, ir tai pakartojama 25 kartus, susidaro visa Amerikos populiacija.
