The out of shape guy living in fantasy land. Oblivious to the fact that you don't get to choose the day, hour, or place when evil comes your way. In the literal struggle for your life, there is no "time out" or recess.
I always get a laugh at the overweight preppers & militia men on Youtube who couldn't walk three flights of stairs at a normal pace without being out of breath, and even one flight of stairs is taxing for them, but they pontificate on how to survive and execute special combat tactics. They're all gonna die ugly, no matter how big their groups and how many guns they have strapped.
Don't crow too loudly. Age comes with material advantages and lessons learned:
I can shoot farther than you can see. Being "in shape" isn't gonna help unless you can cover a mile in 10 seconds.
Me and my atv can go anywhere a man can walk. Not that I need it, I've worked construction 35 years now, farming before that, but it is a whole lot quicker out where I live.
Can you see at night? Can you keep from being seen at night? Some of us can.
Do you keep cash, gold, or silver in your bug out bag? Not everyone you meet is your enemy, or friend. I don't have a bug out, but a "bug back" bag to get back home, even on foot if I have to.
My truck gun is a scoped 308 battle rifle.
How many armed and trained people in your home?
Just some food for thought.
