First, this is not entirely true. Cancer is a result of Epigenetics, (which is currently being mapped out after the genome project), where bad DNA segments have been activated, this can be reversed with a healthy life style and with less stress, and with a protein called genesine.
My definition was a basic and standard one, all you have done is gone into more detail
I agree that a healthy lifestyle and lower stress can help with cancer prevention, however this is not always the case. To imply that all that is needed to be free from cancer is stress reduction and meditation is nonsensical
To assert that "stress is the main reason for cancer" is also nonsensical
Second, 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."
Firstly it is not yet fully established if ageing is due to telomeres, due in part or not at all
I agree that stress can help people live a longer life but that is a different ball court to the original claim
Incorrect, during the paleolithic age disease was virtually non-existanant as the main diet was berrys, nuts and rarely meat. The only cause of death was physical injury.
Due to low level populations
Second, there are modern day hunterers and gatherers who prove this by their long lifespans. The Tarahumara tribe of Mexico, have zero disease, low physical injury, and long life spans with an average of 100-115. They can run for days without getting tired, and are able to catch up to fast running animals as the animals become tired and the Tarahumara don't. However the Tarahumara do not eat meat, their diet consists only of corn. There are many modern day hunter and gatherers in South America, such as recluse areas of Peru, where also the average life span is around 115.
Good for them however on average the Human life span is increasing and not decreasing, as was claimed
