High output-current power sources like this, including 5V/12V computer
PSUs, can cause severe burns if short circuited by a ring or watch strap.
I learnt this from an old and bold computer technician who told me he
had found out the hard way during his apprenticeship. That would have
been when PSUs needed to deliver 100s of amps, but I wouldn't like to
test his advice even with a modern PC's PSU.

The 'moral' is obvious :-)
