"How Beer Saved the World"

So a little while ago I was bored, browsing netflix and came across this documentary called "How Beer Saved the World." 

The documentary was equal parts ridiculous and interesting.  Basically it talks about different aspects of how Man's love of drinking beer has played a direct role in the development of major technologies and traditions. 
Some pretty remarkable and unjustified claims are made in the movie (such as beer is solely resposible for the development of agriculture, civilization, mathematics etc) most of which I would strongly discourage people from believing but I support them as hypotheses and topics worth thinking about.
Some of the other more specific topics seem a lot more viable and evidence-backed such as the fact that the wort-making process actually pasteurizes the water providing people with a fairly clean and nutritious alternative to foul drinking water in the middle ages.  Also in the documentary a chemist is interviewed who (possibly) finds traces of the antibiotic "tetracycline" in the residue in old brewing vessels from thousands of years ago as a natural byproduct of brewing making beer a legitimate medicine at the time.
Like I said, the movie had a lot of ridiculous aspects to it and the narrator jumps to some pretty lofty conclusions making it hard to watch at times but I did feel like I learned something from it and gained a deeper appreciation for beer from watching it so I'll link it to you guys (it's on youtube) here if you want to watch it:
