There is one similarity and one difference between...

(a) Teaching people how to save on airfare by wearing wings and flapping until they get to where they are going, and (b) teaching people how to perform manual CPR:

The similarity is that we're teaching something that most who need to cannot do. The difference is that a small number are able to perform guideline-compliant CPR.

It should be noted that the age distribution of the cohort approximated that of cardiac arrest victims.

For each of the four  groups, the upper-left point is what everybody in the group can do. The lower-right point is the best anybody in that group can do.

That's why my wife and I have a personal AED.
