every one of us should have some knowledge what life is and what are we going through. God have created Adam and Eve from his rib and they were living in the heaven until they made unforgivable sin and must have been punished. So they have been banished from heaven to earth and given time to prove their selves to be worthy for heaven once again. So we need to understand that it does not matter how well you live here, what fortune you have or what you represent in your life, because all of this are human valuable. since human race was brought to earth, humans are trying to worth that they are worthy for other persons but don't understand that this life is exam for god to evaluate us. So good people dying earlier because they have made many kind things and very few mistakes that they have already proven that they are worthy for heaven once again and they have nothing left to do on the earth. on the other hand very evil, bad persons die too fast because they have no more chance, what should they do to overweight their sins? and because they don't deserve forgiveness , they go straight to hell. and persons who are between very good and very bad live longest life span. they are struggling between heaven and hell. god is giving them many chances to prove their selves. So when someone dies early cry for your feelings and love but not for him/her because they have gone to better place, where they have always belonged to.
