240V AC never did me any harm.

I first remember it when I moved a lamp in the loft (attic) which my
father had left there with the base off with live contacts exposed.
It was unpleasant but not harmful. I only just manage to avoid putting
my foot through the ceiling.

The removal guys refused to disconnect the cooker (stove) live so I did
it for them.

 Same here. Having dry skin helps a lot. There are still two real dangers
though: wetness in whatever form and accidentally poking your finger into
a socket where there's a live strand sticking out which punctures your
skin. That's when you can *really* get a belt!

It can also get nasty when muscle goes into spasm and contracts a hand or even just a finger round the conductor, so you can't get free easily.
My first unpleasant experience was with a 350V DC supply in a valve radio which I was trying to fix. I was holding the DC+ wire ready to resolder it to the smoothing capacitor. I had removed the capacitor from its mount, but it was still connected to the rectifier on the negative side. It wasn't in quite the right position for soldering, so I just went to pick it up to move it. I had completely forgotten that the case was connected to the -ve side, and got a hell of a belt from it. My hand contracted around the capacitor, and I wouldn't have been able to let go but my arm muscles also contracted and I involuntarily threw the capacitor 15 feet across the room. That broke the connection, but to this day I don't know why I hadn't turned off the power to the radio before resoldering. It could have been a lot worse.
