Store at least 1 gallon of water per person per day for 3 days, for drinking and sanitation. Try to store a 2-week supply, if possible. You should consider storing more water than this for hot climates, for pregnant women, and for persons who are sick.

People generally can go without food and water for about two to three weeks. This will vary based on underlying health or illness. For people who are very ill, with little body fat, survival may be much shorter.

How long can you survive by drinking pee? An extra day or two, at best. A healthy person's urine is about 95 percent water and sterile, so in the short term it's safe to drink and does replenish lost water.

But one week is a generous estimate. Three to four days would be more typical, especially in difficult conditions like broiling heat. "You can go 100 hours without drinking at an average temperature outdoors," Claude Piantadosi of Duke University told Fox. "If it's cooler, you can go a little longer.

Most dogs can go three to five days without food, while in some cases they can survive seven days or more. However, if your dog won't eat for more than two days, we recommend that you talk to a vet. A bigger issue is water intake. Dogs can go far less without water than without food.

In one of the most shocking tales of survival-at-sea ever told, a man lived for almost three days inside a sunken ship at the bottom of the ocean. In May, a tugboat with a crew of 12 was moving through choppy waters off the coast of Nigeria.
