Question

Can life subsist on anything else but water?

Answer 1

In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.

Answer 2

You can subsist yourself on a certain beverage but not for a long period of time.
I believe the most you can go without water is a little over a week. Not long.
You wont die from it, but you will be extremely dehydrated. <span />
