This may be the only thing we can do if we want to prepare for a really bad situation where medical care is really, really expensive. After all, how much can we do for ourselves anyway? Can we give ourselves root canals? If we have to do DIY dentistry, how about DIY open heart surgery?

In a prolonged TEOTWAWKI situation, I guess we'll just endure the pain, lose our teeth, die of heart attack, etc., like our ancestors did. Modern medicine requires a huge supporting industry in order to work. It's not just some guy with a box of herbs.
