Life is unpredictable. We cannot predict when 'the time' comes. God, He is the only one who knows when 'it' comes. If some people say: "Life is unpredictable" or "That's not fear" or something else that has the same meaning with those sentences, they should know why those people die not in a right time. Just like what I say before, they shouldn't die just because of one simple reason!
So people, sometimes life goes like that and before 'the time' comes, we should use our rest times to do anything valuable. Times is valuable, but life is the most.
