In seriousness, even though it’s a crazy magnet, it’s range still shouldn’t be more than a foot I’d guess
So it’s not like it’s going to grab you from a distance

And the forces involved I have a feeling skin will yield if you try to pull them apart, assuming initial joining force wasn’t strong enough to literally squeeze it through your skin… which is very possible
You can do it without issue, but the risk is pretty high
