Oops, typo I mean .7% saline.

I'd say he is wrong (IMHO). Salt depletion _can_ be a problem
(especially with diarrhea) and drinking sea water to replace salt may be
bad due to the magnesium. If you need 7% saline for wounds or eyebaths
then pure salt is preferred over sea water. Hence salt tablets.

Nav,
I was in a survival course this past July. Somewhere in my past I was
told to consume salt when sweating a lot. So I put salt in my
theoretical survival bag. The class expert (some Australian who's
survived every desert on the planet, and whose name I could recall
only if forced to) informed those of us who chose salt that we were
dinosaurs, and we should throw the salt away immediately. I believe he
said I was a victim of uninformed football coaches, to be exact.
Anyway, I was wondering under what circumstances you would use your salt.
