Can't be as crazy as the strain of Jewish religion that forbids ALL work on the sabbath.

I've stayed in a household like that over the sabbath. Once you get the
hang of what's going on, it's actually very relaxing.

I suspect that it's less crazy than everyone else in the country rushing
off to the shopping centre on Saturday to spend money they haven't got
and can't afford on things they don't need. :-)

I kind of envied the Amish their certainty about things. No ontological
problems for them!
