If our ultimate priority is to protect life, there is a case to be made that the typical person (urban/suburban environment) would be best served making their priorities something like this:
1. Awareness and MUC - Managing Unknown Contacts.
2. General health and conditioning.
3. Medical - Particularly BLS, like CPR and first aid, then moving to tourniquet and massive bleeding stuff. (Lone Star Medics and Dark Angel combine all of it into a two day class)
4. Defensive Driving
5. Hand to hand skills. Boxing and wrestling.
6. Less Lethal. OC spray, etc
7. Firearms training.
The order is probably mixed up, but @
Sherman A. House DDS made the case for this in an article several years ago.
