Between life and death.

First what is the meaning of death?
Scientifically, death is the stop cessation of all vital functions of body.
From religion a religious point of view, death is the transfer of our soul from this world to where we will live forever even be it heaven or hell.

Second what is meant by life?
Scientifically, it is the period at which all the body functions are still working.
From religion a religious point of view, it is the period at which our soul is present in our body and it is the period that in which you should find your mission that god created you for it and execute it.
The time between life and death can be represented as shouting shooting/firing an bullet, where the time that the bullet goes out shoots/fires from the gun is represents the time at which we are born and the time at which the bullet rich reaches its target represents the time of death at which your life is finished, and the time between those is your age at which you play, lough laugh/love, grieve, work, cry and do everything.
At the end i want to say that you have a short time to live life is short so you should spend it in doing what you want/enjoy, and what makes you happy, and what made god loves you. You only have a short time and you don't have/should not to waste it.
