Way longer than your average person but I’d start running out of supplies after few months too. I have food stocked up for few months, 90 litres of drinking water and a water filter, 120 litres of diesel plus what I have in the tank, enough fuel to run alchohol stove for few months aswell and I have a fireplace to keep myself warm basically indefinitely.
It’s kind of scary to think that even me whose somewhat of a prepper would run out of supplies quite quick. What does that mean for the average person who doesn’t even have a jug of water stored up.
Also, this is the kind of discussion that would fit well on !zombiesurvival
