Because most of our body mass is water. I think lol.
a man can not survive for a week without water
they die of thirst because you can only survive 3 days without water
About 2 weeks :) <3
2 days
Without water, humans and the different types of food they eat, cannot survive. An average human can only live without water for about 3 days, so if there is no water, then humans can't survive. So, aslong as humans and/or any other living thing that needs water is alive, water will always be a necessity.
They can't survive without oxygen but they can survive with an oxygen mask that scuba divers use and with supply of oxygen of course .
No oxygen, no water and no food would make for a quick demise of a man on Mars.
Generally yes, but that is only on the basis that "men are usually bigger than women, so need more water". However, a man and a women of the same body size will require a very similar amount of water to survive. It is not gender that determines how much water you require, it is size.
With sufficient water and food a person could survive indefinitely. Without water, just 2-3 days in the summer months.
And have him survive? Without air, about three minutes. If they had air but not water they would die of dehydration after about three days. If they had water but not food then they would last a few weeks. If they had their needs taken care of then the average human lifespan is around 79 years.
The dawn of man, seeing as the only reason humans survive is that we need water to drink, and so this must have been discovered with the first recorded incident of humans, or similar, which was about 1,700,000 B.C.
A normal healthy human can survive for approximately a month without food with no long term serious side effects.around 2 weeksThe average human can last up to 7 weeks on a diet of just water during the day and vitamin tablets in the morning without consuming any food. However those who are overweight can last longer, for eample someone whom is morbidly obese can last up to 13 weeks.
