“That’s the first start to prepping...”
Yep, but it is the last thing folks are willing to practice now ahead of the game. Number one and most important is acclimating your body and learning to live without central heating and A/C. There will be no such thing as setting the thermostat when the SHTF. If you cannot live without central now you will never make it when it does happen. Nothing else you do to prepare will matter at all if you don’t actually do this first. It is a prerequisite.

Lived in Florida in the early 60’s. NO ONE had AC. And, since it was FL, central heat in the winter was called long pants & a sweater...
