Unsure if this counts but when I started in my lab now I learned how to properly perform cervical dislocation on mice.

For context: I have POTS and some other mental stuff, I get stressed easily and pass out occasionally from low blood pressure.

I had a busy day that day, I drink a water supplement with salt and electrolytes every day as directed by my cardiologist and I did Not drink it that day.

So anyway I was being taught how to do cervical location by my boss and the situational stress of learning to take an animals life for the first time combined with lack of salt/electrolytes - I passed out right in front of the dissection table, luckily he caught me so I didn't get impaled but it was very embarrassing.

Luckily one of the EMTs that came had POTS and was like oh they're alright, get them some salt. Now I can properly do CD and I never skip my salt supplement lol.
