Your only defense against
brain-damaging events such as an extremely boring
job,
surreal stuff that just happens,
obnoxianism and other
undesirable behavior from people in your
proximity. These things will make you nuts, but you will be a rich nutcase, cashing in enormous amounts of money from the
insurance company.
Oh, and you might even
go nuts in an amusing way.
I'd rather be rich and entertaining than sane.
Popular forms of mental insurance include
friends, with whom you may spend the evening at a
pub, happily
eradicating traumatic experiences from your
cortex with talk, laughter and possibly some
ale.
