Immortality has been fascinating human being from the very first death of human. People throughout the course of time tried in various ways to gain immortality or at least to increases his life span. Its no wonder that scientists from ancient time to the present have involved themselves in this kind of research. No doubt that science has overcome many diseases that caused death in some few days back but the key to prolonged life or immortality is till unobtainable. Recently scientists at Glasgow University say they have found a key genetic indicator of how long an individual will live.They say the lengths of tiny pieces of DNA called telomeres indicate whether a young creature is likely to live long into old age.

Now scientist are trying to find why the length of telomere usually varies? Is it possible to stretch them to get prolonged life?
Their ans might bring a breakthrough in our life span.
