Let's talk about failure

One of the reasons I'm hesitant to chase a dream of mine is because working with computers has spoiled me. Troubleshooting it is almost completely risk free compared to many other fields! Made a mistake? Hit the undo button. Waste the VM and roll a fresh one. You get the idea.
Yeah, doesn't quite work that way with medicine or finance...

I become a certified electrician years ago just because of how much I had to deal with it for concerts and video productions with 200amp-500amp three phase distributions. Anyway you can't make too many mistakes with that without it biting you in the butt - hard. I've seen way to many people get hurt and a few killed over careless stuff.
Saw a couple people get killed from making mistakes with boom lifts as well. People try to take short cuts and move them without lowering it first but they bounce a lot and can tip over.

Yup...

Since so much of success and failure is luck, you maximize your chances by trying as often as possible:
LOL, you maximize your chances, but taking more chances. But you maximize the chance of success as much as your chance of failure

Ah yes, good ole variance...

Can confirm, 120v across the chest does not tickle.
Was building a variable voltage power supply, just got to testing it. Forgot to unplug it when I had my left hand on the case (ground) and right hand grabbed a hot line. 0/10 would not do again.

I've taken 20K V across the chest. Let me tell you, everything just goes black.
-
I found out that my wife takes full wall voltage a few times a week. Apparently she is so clumsy with the wall plugs that this is a normal thing. I can't remember having that happen to me since I was five!

Obviously not at any significant amperage! That's enough to vaporize flesh and nearly enough to get a lingenfiltgenfusltylsif scar

I'll answer for my sock puppet
It was at a full amp but with an automatic limiter that dropped it nearly instantly. It was enough to take me, and I'm not small, into a full cardiac stoppage instantly. I only brushed the contact and I immediately spasmed and collapsed. I was unconscious for some time. It was enough that there really wasn't any pain. Just nothingness.

My family used to have a kitchen sink that was gorunded to the 220v line for the Stove and oven. Yeah. Couldn't hardly go a day without hearing somebody cussing at the sink and stove. lol.

Good lord haha that's something I'd actually get off my arse to fix (which is saying something because I'm pretty lazy at home)

Yep. only heard of a few people living through that sort of thing. while it's technically the amperage that kills, the more voltage the less resistance (and more amperage) to the skin. and the higher voltage breaks down skin and eventually gives you higher amperage to your insides. This is why amperages above the "let go" point kill as it keeps breaking down your skin until there is less resistance and enough amperage to kill you (which isn't much).

Here is the US code requires plumbing to be grounded if it's conductive so if you got a Hot line on your sink with a normal 15 or 20amp circuit it should trip. Granted a Ground electrode isn't enough alone to trip any breakers (a standard 10ft rod will only draw about 5 amps or less) so it must be connected to the circuit breaker panel.

Yeah, it was way more than enough to kill and I've seen my dad get hit by the same system except his was limited by going through the air (the thing arced and got him from several feet away - the danger in a high voltage system.) But the limiter on it limits the amperage to almost nothing the instant that a significant load is put on the system - like when it tries to kill me. So, in theory, it is designed to stop a heart but not to burn you up.

Is that 110v?
We have switches on our wall sockets to isolate the socket. Saves a whole lotta zap
Ā
My coffee grinder holds a bit of charge in it, so even after switching it off at the wall and unplugging it, I have had the active and neutral prongs brush past my arm, I received a small tingle. Now I hold the power button in for a few seconds after unplugging it. -
Yes, 110 in the US. Hopefully she doesn't do the same thing here in Europe with 230V. Thankfully European plugs are safe. American ones practically force you to touch the prongs.

It's 120v most people call it 110v for some reason. But most homes are 240v split phase and most things aside from dryer's, stove's furance's, welders, etc. run off a single 120v phase.
240v gives you more power with less amperage.
