The only flaw in Corel’s logic was that as soon as you’re running Linux, you lose all desire to run WordPerfect, and develop an irresistible need to align yourself with vim or emacs…

An incidental exchange of earwax with your (romantic/sexual/life) partner is — how do I put this? — not particularly noteworthy for a lot of folks…

Track stands! Not a contradiction to your statement at all though: you need to be moving just ever so slightly.

With a fixie it’s easy, because you can pedal forwards and backwards in tiny amounts. With a freewheel, it’s trickier but you get the hang of it with practice. Ideally you’ll have an incline, so you pedal forward to go forward, and ease up to slide back. After some practice I can use the raised reflective paint from e.g. crosswalks as the “incline.” This miniscule motion is enough to balance — and like you said, it ain’t the angular momentum that does it.

I think you need to include energy cost in the preparation stage. Bread requires a hot oven, which is a real amount of electricity — it’s close to $0.40/kWh where I live. From this link it says that a bread maker uses only .36kWh, but an electric oven would be more like 1.6kWh. So bakita single loaf of bread, you end up with a not insubstantial fraction of the total cost going to heating the oven.

Of course, many bulk foods require heat, so it gets a little sticky this way. Oats/oatmeal probably wins out here, as you can just soak them overnight.
