At first glance, "training for survival" struck me as a bit of an odd concept. I fortunately been able to spend a fair amount of time outdoors pursuing both my career (archaeology) and my hobby interests (mountaineering, caving, and scuba primarily). One very soon realizes the need for preparation for unusual events and emergencies - everything from injuries to bad weather and back again.

Probably the thing that taught me the most about survival was several years of active participation in mountain search and rescue in Southern Arizona. That got me further into first aid and emergency care than anything else I have done. SAR provided many "practical exercises" and examples both bad and good.

I think that almost anyone who is at all thoughtful about life will pay some heed to survival preparation, wherever one may be living and whatever one may be doing.
