Reduction of stress encourages the growth of telomere, which allows cells to continue dividing. Our cells divide and grow, a telomere – a small DNA cap at the end of each chromosome - protects our dna from damage. The enzyme Telomerase, repairs the telomeres and ‘keeps DNA young'.
Several new telomerase-based drugs have entered Phase II and III clinical trials. And there is a very real race for the ultimate anti-aging pill.
"Current research reveals stressed people have shorter telomeres. Shorter telomeres appear to predispose us to disease and cancer and lead to shorter lives. Yet astonishingly, it has been discovered meditation appears to stall the process."

Another thing to note, is Epigenetics, the layer that controls your genes, control which genes to turn on or off. A healthy lifestyle turns on the good genes and turns off the bad genes which helps defeat disease. Also, your gene activation combination was passed down to you by your parents and you will pass it on to your kids. This means if your parents smoked and had a bad life style, a lot of their bad genes were activated resulting in disease, this configuration was passed on to you, however if you exercise and eat well, you can deactivate those bad genes and turn on the good genes and pass that on to your children. You could reverse the damage caused by your family tree.
