I'm 41. I've had an EDC "end of the world go-bag" since I was 6 years old. As an adult now, it just makes sense. I have it in my work backpack. I have small ones in each vehicle, along with standard roadside emergency items.
How so? Because I was programmed early on that if the shit hit the fan, you gotta look out for #1. The Great Tribulation could break out at any moment, so at least be prepared.
Ironically, there's an entire industry built up around this type of mentality. "EDC" or "Every Day Carry" can be minimalist lightweight items, or just a small pack (8inx8in for instance) like I carry. Sometimes it goes waaaaay overboard, like in the case of "Doomsday Preppers", that have an entire basement walls stocked floor to ceiling with food items and 50,000 rounds of ammunition. I mean seriously, 50,000 rounds is pretty light duty if you ask me. But anyway, preparedness is not insane, but going overboard can become like some sort of hoarding obsession.
