Perhaps it is best not to take this survival stuff too seriously. The death rate has not changed: it is still one per person. There are no data to suggest that survivalists live longer than other folks. Perhaps the key to survival is to be part of a non-fragile community, implying that time spent at church is more valuable than time spent at the shooting range, or that donating supplies to the food banks might be more valuable than storing supplies in my redoubt.

A gym membership that you actually use would certainly qualify as a "real" survival "basic." Smoke detectors, fire extinguishers and first aid kits also make the cut. I've seen a lot of over-worn tires on cars involved in injury accidents, and many dangerous house fires caused by homes and appliances that weren't up to code and in good repair.

It would also be wise to invest in adequate life, disability, and homeowner's or renter's insurance before investing in traditional survival supplies beyond the minimums. Many people have no disability insurance at all, and many carry the minimum legal or grossly inadequate liability policy limits on their homeowner's and especially auto insurance. These omissions can inflict real hardship on you and your family, and cover harms far more likely to occur than a major disaster.
