I completely agree that Being trained is by far the best.

Yes proper selection of traveling companions is nice.

The problem is if you get into a bad situation you rarely have a choice of when or where. Also you may have "0" choice who is there with you.

It sure would be nice to know ahead of time when an emergency was going to happen. We could either avoid it or have all that we need to deal with it.

Cheat sheets do 2 things. First they have a calming effect even on the most experianced person. Have you ever drawn a blank. Sure you know it like the back of your hand but you just can't get started. second others around you may not be as knowledgable as you. Maybe you are the one out of the action.

Sure you could bleed out rr die from a heart attack while the other guy is reading how to help you. But at least if the material is there your chances are better.

Mush more conveniant.

I also fully agree that in many situations you have to do it now or else. But also remember the first thing in the STOP or SURVIVAL acronyms is to stop and sit..
