The book specifically looks ideas including; how biological age is not chronological age; a biological basis for the mind-body connection, how sleep and diet can affect telomeres and shockingly how mothers who are highly stressed during pregnancy have children with shorter telomeres. It also offers tools and advice on how to determine cellular age and telomere health.
