Depends on person. I've accidentally touched 220V several times and only felt a little stinging. One time I was kneeling on wet grass. But - please don't try it yourself, I'm just very lucky and probably a bad conductor, you might be not.

You need thicker wires and higher current to carry the same power. In Europe electric kettles are much more common because they can use up to 2kW in most households without any problems.
