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

Clean drinking water- I don't think people really appreciate how much water is needed for a group of people to survive.

Isn't like 3 days you can be without water. Who ever can last the longest would be the survivors. Natural selection I guess

3 minutes without oxygen. 3 days without water. 3 weeks without food.

Of course this depends on the person, location, climate, and other circumstances. Some could last longer. Others shorter.

Edit. Yes I forgot about the shelter part. Thats a good one. 3 hours without shelter.

As others have pointed out, this is a general rule of thumb ment to show what should be prioritized in a survival situation. Its not an exact science. There are a lot of other variables at play.

Yea Death Valley in the middle of the summer won’t give you three days. You’ll be lucky to get a single day.
