Thanks for the reply. I know that my digital thermometers would be toast if I'm still around during an EMP attack; how would a long term outage be a problem for battery-powered devices as long as I have batteries? That and an old fashion thermometer is hard to find.

At my level of experience, I don't see how knowing the exact blood pressure would be beneficial.
