Rubbish. People who have an IQ of less than 186, may well find that their
watches still function after a lightning strike. ...snip...

Just jumping in for the fun of it. IIRC, Jax claims an IQ of 154
*based on the MENSA IQ test*. This test uses a standard deviation of
24, instead of the more typical 15. Therefore, his claimed IQ, in
numbers most of us are more used to using, is in the low 130s.

As to the original question, I'd vote for refrigeration; I love
refrigeration. And, yes, I'd bring along my sextant (mostly 'cause it
gets bored just sitting there doing nothing, although my slide rule
keeps it company). Obsolescence sucks.
