acetylsalicylic acid does say SOMETHING about the structure for the molecule. With just that, you can draw up half the atoms (assuming that acid refers to carboxylic acid, which is not that risky a bet).

From what I gather from the literature, you are right about the hangover, but wrong about the mixing with alcohol. The blood concentration of the toxic degradation product is lowered when paracetamol is taken with alcohol, probably due to the alcohol successfully competing with cytochrome P450 in the liver, in much the same way that alcohol can be used to treat methanol poisoning (though another enzyme is competed for here).

However, there seems to be no reason to not use inbuprofen or naproxen:

Except, of course, individual problems, like you mention with Tylenol.

There is no "mass" in reality, it is just a concept we havr made up because it makes a whole lot of equations easier. Or, in the logical extreme, there are no particles, only clicks in my Geiger counter.

That's why I wrote "in the field". I don't know how lettuce seeds are grown, but as each plant produces many seeds, muchless land is needed. It could even be grown in greenhouses where you could also keep pollinators.

On the other hand, you get produce that hasn't been in the store all day, and that 10 other customers have not picked up and put down again.

That depends on the store, some do have special offers in their web store.

Lettuce isn't a fruit, so lack of pollination on the field shouldn't be a problem, tomatoes and potatoes are from the new world, and wheat, oats and rice are wind pollinated, so pollinators doesn't enter the equation. However, I think that is close to a complete list of crops that wouldn't have a problem.

Does the plants take it up from the soil? Things that bind that well too the soil tend to have low bioavailability.

I think I have seen a documentary where a snake was coiled around its eggs. IIRC, it even had muscle spasms to supply heat. Snakes are cold blodded, right? Or can an animal be warm blooded part of the time?

That would mostly be glyphosate, which is definitely the least bad pesticide to eat. If the glyphosate- resistant crops have less of other pesticides on them because glyphosate is used in stead, they are probably more healthy.

Conversly, if it weren't for the French, you would be writing English.

Wouldn't this lead to more flash crashes, where everybody tries to sell at the same time if a company does badly, as everybody can react to the news simultaneously, and know that they don't get another chance for a month? And everybody is afraid that somebody knows more, so they are more eager to sell?

How does it hurt productive industries? This blip was short enough and small enough that no-one except high frequency traders should be affected.

On the other hand, it does serve some purposes: It decreases volatility (at least, it seems so from the data), and in reduces the bid-ask spread.

It could increase the volatility. If a tax was introduced, it wouldn't make sense to trade for small changes in price. When the prices change become large enough that it makes sense, the people selling would drive the price down further, leading more people to sell.

It would also lessen the liquidity, leading to worse prices. As it is today, I can sell my stock to HFTrs at close to the current value. If there were no HTFrs, I would have the choice of selling now at sub-optimal prices now or waiting in the hope that somebody would at some time would meet the price I want.

Whenever something sounds too good to be true, you have to ask yourself if it is. In this case, id it were that easy, why haven't other people done it? My guess would be that the price development is clear in retrospect, but hard to predict. How would you know when it is going to peak? How would you know if the bottom have been reached, or if it just plateaued before the real drop?

In the long run, it is really hard to beat the market.
