A review by reinhardt
The Telomere Effect: A Revolutionary Approach to Living Younger, Healthier, Longer by Elizabeth Blackburn, Elissa Epel

4.0

How our lifestyle gets into our cells: Telomeres. Telomeres are the repeating bits at the end of our DNA that protect the DNA during replications. The shorter our telomeres, the older our cells. Older cells don’t work as effectively for thing like fighting off disease.

Stress also has a notable impact on telomere length. More stress, shorter telomeres. Or at least more negative impacts of stressful situations, the shorter the telomeres. Our attitude to stress is important. Seeing the situation as a challenge instead of a threat protects our telomeres.

Pessimism, especially hostile pessimism has a devastating effect on our telomeres.

Telomeres also show our activity level. Endurance exercise and interval training both lengthen telomeres, and improve our immune system and longevity.

Healthy eating and good sleep also help our telomeres.

And our telomere length at birth is directly related to our parents, especially mothers telomere length when we were conceived. The mental state and health state of parents have a direct, permanent impact on a child.

The book summarizes a large number of studies, a good chunk will turn out to be non-replicable, but still a lot of interesting information here.

A downside is the book is a bit repetitive and does get a bit far off track on techniques for reducing stress, but worth reading.
