life and death

What is life and what is death?

At certain points in life, I believe most of us would have asked ourselves this question. I don't think there's a true answer to this. Why do people sometimes just go like that? This we will never fully understand. Some say fate. But can fate never be changed?
Some things will be left unanswered forever. Research and development may be rapidly growing but can one be absolutely sure that the findings are a hundred percent true? I doubt so.

Are the past beliefs true? I really would like to know. But I guess it's something we humans can never find out. Are they just myths waiting to be retold? Or are there people who came back from the dead to tell the living about the world on the other side.

What happens when humans die? Different people believe in different stories. How I wish some day soon science can explain everything. But on the other hand, I feel somehow that it's daunting. Maybe some things are better off left unsaid or unexplained.

A fine line can be drawn between life and death. Many a time we see people just pass away for almost no logical reason. So is there a distiction between the two. The line seems blurrer now that many scientists and psychologists from all over the world are trying to investigate life after death. It indeed causes our hair to raise sometimes, when unbelievable findings rip into our minds.
