Let's face it, we all touched 120V before we were 4 years old lol
I kinda doubt some of this stuff..... When I was 10 I apparently touched the 250 volt "B+" line in a 1930's console radio (called that since portable radios had A batteries for the heaters, B for the plate (tube) supply;, and a bias 'C' battery for the grids) by reaching around the back of it and apparently glancing across a tube pin, and while I don't remember touching it I remember picking myself up off the floor sometime later....
The only other time this happened, was when working as a maintenance electrician in a food processing plant at 23 years of age, when someone complained 'there is something wrong with this Conveyor Line'. As it was on the only floor of the plant that had 277Y/480 I was trying to be 'extra careful' but just touched the conveyor, and sometime later, picked myself up off of a puddle of water on the floor....Of course, the ground wire at the plug of the unit had come undone, and the cleaning water was causing conduction to the case.
Most 120 volt to ground shocks are much less eventful, but there are some industrial settings in the states with 240, 277, 480, or 600 to ground, and I'm not even sure about surviving a good 240 volt shock, or even a shock off the DC side of a series string solar panel installation (my house runs around 450 vdc)....
But for most homes (99.9999% of them), in North America, all shocks are 120 volts, whether the branch circuit is 120 or 240.
But a local school just 'modernized' from 120Y/208 to 277Y/480, and a week after the job was complete, a fellow electrician was electrocuted, something that hadn't happened in the 75 years the school existed up until that time..... So even electricians need to be reminded about safety - although on those larger circuits most electricians actually die from 'arc flash trauma' (like being in the middle of a bomb). 208 volt circuits will usually 'burn clear', whereas the 277 volt stuff is just enough to burn and explode out of control. Current limiting fusing and 'lug limiters' are always a good idea for that kind of thing.
