how are telomeres connected to ageing?

Kill chromosomes: The telomeres are the material that protect the end of the chromosomes that contain the dna-genetic material. They shorten with age and when they become too short, the chromosome does not survive. They are what protect the genetic information so it can be transmitted from one cell to the next.

Telomeres: Telomeres are the caps on the end of chromosomes. Every time a cell divides the "cap" gets shorter. When the cap reaches what is know as its hayflick limit the chromosome begins to fray (like a shoelace when its cap breaks). Then the cell dies. Telomerase is the enzyme that makes telomeres longer. Healthy lifestyles have been shown to activate telomerase thus slowing cell death.
