Bite me.
Some people need modern medicine to live. If the SHTF, a LOT of people are dead.
If I were to bite you, you’d go septic and it would be a fairly merciful and relatively quick, though painful death. :O)
I take BP meds. Guess I’d have to try some herbal remedy or the other along with praying a lot. (I got on a cut rate program last year where I ordered a 6-month supply of the meds by mail and got large bottles of pills.)
