Dunno why US uses 110V, but 220V means less current, which means less
powerloss in cables etc.

Again, dunno why US uses 60Hz, but 50Hz is less lethal (ie. you need
more current to distract your heart) than 60Hz. This has something to do
with 60Hz almost syncing to some multiply of normal, health heartbeat.
Don't remember the details (I was told this at school something like 12
years ago).
