As lets be honest its probably highly likely now, what with events in the M.E. and northern africa, world economies on the brink of collape, probable food shortages and loss of oil supplies/ soaring oil prices.
So say for instance there was like a zombie apocalypse after the impending global nuclear war, you have survived but are living in a wasteland desecrated by the aftermath of nuclear conflict, there are zombies everywhere and food is contaminated etc. I'd say there is like a 50% chance that we will see this in the next 5 years.
But tbh, I will just go cannibal and lock and load. Tbh I've been stock piling baked beans for about 6 months and i have at least 200 tins under my stairs. I also have 45 bottles of evian water and i add several to this every week on payday. I also have a decent collection of air weapons and i think if the SHTF I'd fair better than the average man, also I am a veteran martial artist so i'd be able to look after my self in a hand to hand combat situation.
So what is your plan and have you started making provisions for the impending apocalypse ?
