Because you already found out, what is one thing you’ll not fuck around with?

I've inhales acid fumes a couple times and every time it's a hard lesson to not do whatever I just did. Unfortunately it's a pretty common hazard in my line of work.

Jumping off cliffs into water.

Broke my back. Never jumping off anything again. Very lucky didn’t get paralyzed. 9 months physical therapy and still weird random pains 2 decades later

Living creatures.

When I was a small child like 4 or 5ish I poked a cat in the eye (dont recall if intentionally) and he scratched my face immediately. That day I learned what karma was. Always believe that if Hurt someone or something they may hurt you. That's why I give snickers to the crazies at work.

Mixing household cleaners.

I tried to clean a stubborn stain in a toilet once. I used a toilet bowl cleaner and it just wasn't doing the job. In a fit of pique and stupidity (pique stupidity) I took a bottle of bleach and dumped it on the stain.

I knew something went wrong the moment I saw the bubbling. And the weird green stuff coming from the toilet in what looked for all the world like stranded smoke. But green.

So I hastily looked at the toiler bowl cleaner ingredients in the huge warning label that specifically said not to mix it with bleach. A quick formula translation in my head later:

NaClO+2HCl→Cl2+H2O+NaCl

Fuck.

I fled the bathroom and ran to the balcony as chlorine gas filled the apartment's lower half, spilling out of windows as it filled to that height, following me out the balcony door and bathing my legs up to my knees in chlorine as it spilled over the edge, with me leaning as far as I could into fresh air so I wouldn't breathe it in.

After what seemed like forever, I was able to hazard going back inside. I then opened the front door and set fans in each room to blow toward the hall where fans blew the air out the front door.

Two good things happened from this.

1. The toilet had never looked cleaner. It was like it had been freshly installed straight from the factory.

2. There were no living vermin in that apartment. From the smallest dust mite on up.

Ever since then, I don't mix household chemicals. Ever. Even if I "know" it's safe.

Heroin. My childhood friend's mum let him try some when he was about 13. By 15 he was tricking for smack. By 17 he'd got AIDS and died from suicide. I supposed I watched my friend find out, but his mother really ruined his life.

wild animals... all of them.

i will not touch them, will not interact with them, etc..

i enjoy seeing them (they are cute, majestic, etc.), but i leave them the fuck alone.

Electricity. I got a very mild shock once and decided I just don't ever want to fuck with it in a way that will kill/maim/injure me.

Drinking alcohol while taking medication I was not supposed to drink alcohol with. Was a fun night until the alcohol poisoning happened at least!

Geysers.

I stuck a finger in a geyser-adjacent hot spring to see how hot the water was, and my finger burned for three days. Don’t fuck around with geysers, y’all.

Alcohol

Electricity, crossing the street not in designated place, reading instructions on household chemicals, eating raw food, eating unripe fruits. Basically everything that we teach children not to do. 🙃

Condoms and safety pins

Riding a motorcycle.
