When a person is dying, he or she will get very lethargic, the body functions will slow down, wounds may not heal as fast, blood pressure may drop, and there might be difficulty breathing. A person who has lost all consciousness of his or her body, has no heart beating, and the body has stopped functioning is dead. Scientifically, we don't "go" anywhere. Our cells merely lose their function and we are not alive anymore; we cannot take in energy, reproduce, or have any cell function, which are three main characteristics of living things. Notice, how often I have said "cells". Cells are an integral part of our body because we are made up of them. If there were no cells, we wouldn't be alive. When our cells don't function, they die, and we die. Where we "go" after death is based on a person's personal belief.

That is a great question! When people die and are buried they eventually decompose. Decomposition is a natural process by which your breaks down into the basic building blocks of life. Our molecules can then be used to build new life.

What happens to your consciousness when you die is unclear. It is thought that once you die, your thought processes simply stop and you cease to exist. There is no way, currently at least, to scientifically test whether or not a soul exists.
