But I can say now, I understand. Pepsi recently came out with "1893", named for the year the company and was founded, and it allegedly is a recreation of Pepsi's original recipe. Before high-fructose corn-syrup and mass-produced soda machines, there were just bottle of Pepsi made with more "normal" or "natural" or at least "approachable" ingredients. While 1893 isn't my favorite drink ever, it was actually pretty eye-opening to see how people could have come to accept it as "normal" and how it paved the way for the modern Pepsi empire we know today. It's the missing link between nothing and everything.
Nothing comes from nothing (a tautology if I ever heard one). Therefore, if you're confused about something's origin, you might just need to look a little closer for that missing "1893" link.
