Not realistic for this hardship

The end of the world as all of us assume it is coming sooner than all of us can even imagine.

I am not one hundred percent sure as to how it is going to end, but I have a strong feeling that with all my heart that something is coming.

I think the aliens will come & attack our planet, causing us to have to live low & hide. Perhaps zombies will attack, and all of us will have to spend our time surviving and making food.. Perhaps we will slowly kill the environment & make it unsafe, but either way, all of us need to be prepared for hardship, & one of those ways is by not relying on our Heating & A/C equipment. I have zero problems with Heating & A/C equipment, however constantly temperature control has killed off the ability to handle hardship! Our forefathers used to build fires for warmth. They would walk directly through jungles & up mountains without any help from an air conditioner. Those women were manly & tough, & they didn’t need an air conditioner to make them that way. The warmth was seen as a means of survival, not as a means to make you comfortable, however, I won’t tell people to call it a quit when using their Heating & A/C equipment. The weaker that people in the world increases our chances of survival in a terrible situation. If you can’t live without air conditioner & furnace, you entirely won’t last a very long time in an extreme environment! Go ahead! Sit back & adjust your temperature control and just ignore all of our advice. I will be preparing for whatever is coming up next. I will do so by refraining from using any Heating & A/C device in my bunker!
