Interesting. Thanks for the great explanation. I had always been confused because whenever someone in my family had an infection they would be given antibiotics so I assumed they were inherently good to take. Yet seeing no antibiotics on dairy products the other day threw me for a loop as I’d always thought they were good for people

Probiotics and antibiotics are two opposite things; why would you assume they are both good or bad?

Probiotics are meant to stimulate the bacteria in your gut, which are already present, so making them more active isn’t a huge risk. Antibiotics kill bacteria throughout your body, including in your gut. Your gut bacteria are very helpful in you digestion of food, so you should avoid killing them unless you need to.

As an example, it’s better to give your employees a bonus rather than fire a bunch of them. A bonus won’t hurt your employees, and therefore your business, while firing employees will definitely hurt your business.

Agreed on most of what you said, with a small correction: that people today have more time and can watch movies, entertainment, etc, because of advances that freed our time. Previously people used to spend a lot more of their time finding and growing food, crafting stuff, etc, mostly during daylight before electricity enabled people to see brightly at night. (so people also probably slept more too)

When an onion's cells are damaged they release a small amount of sulfurous gas (I don't know the exact compound off the top of my head).

When this gas hits your eyes, it reacts with the moisture there to create a little bit of sulfuric acid. This, obviously, would be quite painful.

Running out of money to pay the army or police is a good way to kick off a coup or revolution. It's fairly rare for this to happen though, since most regimes know who they rely on, so any money they do have will go to them. (Though there can be conflicts - which branch of the military should get the most money? Who's more important, the military or the police? The main bulk of the army or the elite units?)

I was on grand jury duty and had a case like this presented. A smallish business used a courier to take checks to accounts. The courier used the account and routing info from those checks to get checks for himself. He would then pay his bills with those checks, except he would overpay. So bill for $120 would get a check for $1120. He would contact the company about the overpayment, and get a refund check from the company. We voted to indict.

Sweet deal, glad I could help and good luck breaking in.

Actually I just scoped out some of your comment history and see you're working in CNC engineering and pop into physics and CAD subreddits a lot...I have an idea for a hand-cranked guitar pickup winder I'd like to design for 3d printing but for some reason I'm having a hell of a time getting my head around how to design the gearbox to multiply RPMs in a reasonable size. A guitar pickup involves upwards of 10,000 winds of a copper filament around the magnetic pole pieces. Motorized pickup winders tend to have speed controls from 600 to 2000 RPMs but for a hand-cranked machine 500RPM seems downright reasonable. We're talking <2oz balanced load. Is that something that might be in your wheelhouse that you could point me at some good resources or fundamentals about? Because I'd love to learn it.
