Something cool: History, part 1 of infinity.
Probably the most important person you've never heard of: Mansa Musa. This king of Mali in the 14th century is responsible for every modern innovation since the Renaissance. How?
In 1324, Mansa Musa travelled to Egypt, carrying loads and loads of gold, 'cause, you know, everyone loves gold. He intended to trade his gold for the riches of Egypt. Problem is, he didn't know the exchange rate. So Egyptian merchants gouged his entire caravan for all it was worth. As a result, Egypt actually ended up with too much gold. Their economy became bloated and overinflated.
Europeans, doing what Europeans do, decided to take advantage of this. Several powerful Italian families took advantage of the lowered price of gold to get tons of it for cheap. And these families included the later-famous de Medicis, da Vincis, di Lodovicos, etc. And once they were rich, the Renaissance began.
So, yeah. History is pretty cool.
On an unrelated note, if you're ever in Mexico, grab a couple of sodas. They use cane sugar instead of high fructose corn syrup like they do in America, so it's actually higher quality.
