Asking medfags and others as well:
How safe plasma and blood donations are? So far i understand that plasma is in blood and that gets separated by the machine while the rest of the blood is pumped back in.
Plasma(blood as a whole as well) seems to contain lots of precious things the body needs which is extracted in the process thus there is less essential liquid in your body.Sure it gets regenerated but wouldn't this put more stress on your organs to make up for the inbalance thus shortening the lifespan of them also cause some hormonal problems due to less plasma - and with that hormones - in your body? Are there non-disclosed side effects of donating long term? My grug logic would say extracting essential fluids out of your body would cause problems but i'm not well equipped with info regarding this.
Any info is appreciated.

What would happen if you managed to connect magnets on the same pole?

Does your IQ raise during an adrenaline rush or does your brain reach its max processing ability? Doesn't cortisol help with strong memory creation? Assuming any of what I said is true shouldn't you just have a panic attack to study instead of being bored?

What now /sci/?

Any other shrigmas around right now? Here's my brown champignon mycelium

For reasons I can't explain. I need to come up with an equation with a magnetic vector potential A, complex unit i, mass m and two eulers numbers e. Throw pi in there too for good measure.

Doesn't have to do anything, just look good
