I asked a similar question last Fall. Here’s a link, just for reference.
I was feeling pretty optimistic about my chances at that time, having a lot of camping experience, and feeling like I’m pretty resourceful in general.
But the general consensus was that a few days ‘roughing it’ out in the woods with food you brought with you from the store and camping supplies from REI is nowhere near the same thing as a real survival situation. And they’re probably right. I’m generally in decent health, take no meds, but I’m old and out of shape. In my younger days I’d probably do better than some, and even today I think I’d have some skills I could bring to a tattered but hardy band of survivors. I’d maybe last a few months, maybe even a year.
BTW, I hate to be that guy, but it’s so perfect I can’t resist: great username / post combo!
