On Death..or Life?

Death is easy, living is hard. Yet every single living creatures is struggling to survive, to live. Suicide is a sin, and longevity is a gift; sometimes an achievement. Perfect health doesn't guarantee longevity;some people with perfect health and die sooner than those who are squandering their health. Some failed suicide attempts, some were unborn. Life is more appreciated when there is death, more loved although it's a struggle.

People try to live healthily so they don't die, and "achieve" longevity. But isn't life is a gift? Then why we live healthily? Qualified life?

Why people want to live long? So they have more time to make up their mistakes, and do some more? Or to have most of it? Isn't heaven is incomparable to life on earth?

Life is more on getting, receiving, or giving?
