Interesting concept, certainly something to do solo and not with a group of buddies or family, with you 'roughing' it and them having some comfort.

I will say this for myself, I go use my EDC items on a regular basis, except the space blanket, (to hard to fold back down to the small size, though I do have another I use for demonstrations, tests and such).

I think if anyone has a EDC kit or 'survival' items and doesn't take out the items and use them, they are setting themselves up for hard times. These pieces should be used as frequently as possible and replaced when necessary.
