No lie, I love yeast.
Sourdough, other baking, nutritional/flake yeast, vegemite and marmite, it's amazing how one teeny tiny little thing can start reproducing and burping and feed us so well, while being incredibly yummy.
Then there's every ethanol containing beverage, which isn't exactly my favorite yeast product, but look at all it can do! And it can be used as fuel, so there's that.
They're everywhere, and that's so damn cool. Plus, have you seen the sexy little buggers in a microscope? Just wiggling around all naked, getting it on with sugars and reproducing for our pleasure. I mean, who can blame humans for being aroused by yeast sex!
