  Why do we die? In order to understand why we die, we need to understand
why we age; And this has something to do with a relative decrease in
Telomerase concentrations. Telomerase is the enzyme which recognizes a
certain sequence repeat at the end of chromosomes. It consequently adds base
pairs in an unusual structure that may act as a protective structure of the
chromosome ends.  As telomerase concentrations decrease over time, more of
our chromosome ends lose the protective structure and pieces get degraded.
Chromosome ends get chopped off, DNA is lossed, and you begin to age....
