It is impossible. So just give up. What I do is that I let my destructive nature take hold. I start scrutinizing my work now that it is too late to fix it and start mentally going over my procedure thinking about every step I may have fucked up.

I keep doing this for about an hour and then my destructive part gets tired and goes away and I go back to other things.

You can't fight it. If you try to distract yourself or calm yourself you will just feel shittier. All that you can do now is kill yourself, hope there is a god and an afterlife, then go to that god and kick him in the nuts for designing us like this.

Finally finished all the math needed so I can get started with actually QM i.e. third year physics.

Feels good. After all the math this is easy. After this, solid state physics, thermodynamics again, classical EM again.

You'd need constant oxygen circulation, which I assume would require equipment larger than the fish itself. Why not just design a fish mech? Then we can have our bettas role-playing as clanners in their mini-stormcrows.

I have been reading a lot of /x/ tier conspiracy-esque articles lately about most things. What tends to pop up a lot is ''pollutants'' in the air, water and food etc. Is there any ground for this to be a valid concern, or are the conecentrations of pharmaceuticals, and other stuff simply too low to impact a third party interaction with these substances?

t. haven't had a glass of water in 50 hours

if someone ever tells you "X is a mind control drug, a poison, a sedative" etc., you need to realize that too much or too little of any one substance can cause problems. Poison is about the dose, not the substance.

Well actually there is an annoying contradiction with the argument FOR fluoride.

Their argument says:
Statement 1.) its good for teeth and oral hygiene
Rebuttal 1.) it only spends a minimal amount of time on your teeth before you swallow the water and it goes straight to your stomach, and if it somehow crosses the gut wall, it will cause flaws in those same teeth and bones.

Statement 2.) Well if its not good for your teeth it must be there to kill bacteria. Yes, that has to be the reason.
Rebuttal 2.) If it can kill bacterial cells it can sure as hell kill human cells, therefore its bad to swallow and ingest fluoridated water and products.

Statement 3.) No see your human body has billions of cells and therefore can afford to lose and replace a few, whereas the water supply is not contaminated by billions of cells its only a few... losing a few cells through fluoridation is much more preferable than loosing... a few... cells... from bacteria... humm
Rebuttal 3.) Who decided that i had to choose between those options. There are chemicals slightly more safe than fluoride, why arnt we just using those instead? This is a restricting the options fallacy. And lets not forget the government doesnt say that fluoride is an acceptable loss, it says the fluoride is completely safe to ingest throughout the course of ones life. We could easily see a latency period in the effects of fluoride and it could be our generations version of asbestos.

As you can see ive demonstrated here that the logic behind using fluoride is deeply flawed. Atleast its a restricting the options fallacy or even a necessary and sufficient conditions confusion fallacy.

However if someone tries to link this with a global conspiracy that is somehow all powerful and responsible for the reason they as people cannot get ahead in life; like ancient aliens or devils then this is most likely a circular argument fallacy.
