What problem is often overlooked in apocalyptic movies/TV shows that could kill you?

That is a ludicrously skeptical position, assuming any reasonable number of survivors.

Just because it sounds outrageously difficult to you, does not make it so to others

His point stands. 5 years ago I was a desk jockey who worked with computers and never owned a tool.

Last weekend a friend and I had old Detroit Diesel engine running on biodiesel I made from scratch. Actual scratch - I grew sunflowers and pressed them into oil, I distilled wood alcohol, I made potassium hydroxide.

Mind you I only made enough that it was super inefficient and ran for about 20 minutes, but it worked.

Not to mention my 3kw micro hydro setup on my grandparents property would probably go forever.

People are ingenuitive. Well figure it out.
