It is a cycle of nature that every living creature will die whether you are a human or animals. By lapse of time, every young creature will slowly turn to be old and then disappeared into dust. We are human creature and the destiny is the same.
If you come to an old age and die, it is normal. But, some people who die young or before the average dying age, is something to be discussed. They die in sickness. It is because they neglect to take care of their health and catch some sickness which causes them to die at an age they should not die.
We do not have to scare about our death in an old age. It is a road of “must” for every body and what we have to do is to cherish our living days as long as we can breathe.
We cannot resist accident which may fall upon us suddenly if God has chosen us to go to heaven. But, apart from accident, we must try our best with our wisdom not to let sickness of any kind to fall upon us.
We have to live a good life every day, sufficient sleep, balanced food, adequate exercise, peaceful mind and anything which can help us to live on.
