Classic.
The young Millennial, who probably only has "physical fitness" covered, is playing up the primary importance of physical fitness. I've seen this a thousand times. Everyone wants to be a winner. Whatever you're good at, wherever you're all set? That's what you say is most important in life.
If you had a couple of those G's covered (say, Guns and Group) you'd be secure enough so that you could GET in shape in the early days of the collapse. The group would look out for you in the meantime. Just for starters, the Group would implicitly include many of the other G's!
Classic.
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.
