These studies have uncovered several observations about starvation: An article in Archiv Fur Kriminologie states the body can survive for 8 to 21 days without food and water and up to two months if there's access to an adequate water intake. Modern-day hunger strikes have provided insight into starvation.

One study in Archiv Fur Kriminologie concluded that you can't survive more than 8 to 21 days without food and water. People on their deathbed who are using very little energy may live only a few days or a few weeks without food and water. Water is much more essential to your body than food.

The red blood cell survives on average only 120 days. Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled.

There are no precise answers. In general terms, the human body can go two to three days without water and, it is often said in survival guides, 30 to 40 days without food of any kind. (Many of these guides also discourage people from scavenging for wild plants or shrubs because of the adverse effects these can have.)

Andreas Mihavecz, an 18-year-old Austrian man, may have survived the longest without drinking water: Police accidentally left him in a holding cell for 18 days in 1979.

Again, as referenced previously, cattle can survive for as long as sixty days with little or no food, but only seven days without water. In extremely hot, humid climates like the Deep South, that number may be even less.

The amount of water weight your body stores can vary a lot, but the average person carries one to five pounds, Clayton says; athletes (or anyone training at least 90 minutes a day) can train their bodies to stash away double that (a good thing, he notes, because they'll use it the next day).

Harrison Okene survived almost 3 days inside a sunken vessel. 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.

Most people survive near-drowning after 24 hours of the initial incident. Even if a person has been under water for a long time, it may still be possible to resuscitate them. Do not make a judgment call based on time.

It Depends on Your on Your Environment In outdoor environments without high humidity, two to four days is often achievable. This period can be expected to be shortened in high humidity environments and extended in low humidity environments.

A human can go without food for about three weeks but would typically only last three to four days without water.

After ejaculation, sperm can live inside the female body for around 5 days. The fluid in a woman's reproductive tract has all of the nutrients that sperm need for their survival during that time.

Once the sperm is DRY it is dead and cannot travel to fertilize an egg. Sperm can live for 3-5 days if it is in a warm, moist environment such as the vagina or uterus of a woman. Sperm cannot come back to life once it has dried, even if it is pre-moistened.

Andreas Mihavecz, an 18-year-old Austrian man, may have survived the longest without drinking water: Police accidentally left him in a holding cell for 18 days in 1979. It's a fuzzy record, though, since he allegedly licked condensation off the walls of the prison.

Water fast (24–72 hours) During a water fast, you are not allowed to eat or drink anything besides water. Most people drink two to three liters of water per day during a water fast. The water fast lasts for 24–72 hours. You should not water fast for longer than this without medical supervision because of health risks.

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.

The virus can live on hard or soft surfaces for about two weeks; in still water it can live months or possibly years.
