How can we live well and for many years by achieving harmony of body, mind, and soul? We all emphasize our bodies and appearance, less on our mental activities, and even less on our soul. However, these are equally important factors, as both mental and emotional activities contribute to well-being and longevity.

Do we care about longevity if it is not combined with a good and healthy lifestyle? Would we want to live, for example, twice as long and spend half of that time sick and aged? Do we want it? We do not want it! The book highlights ways to increase healthy life expectancy.

What do the biosciences promise today? Are there bioethical issues? Can physics, psychology, and inner philosophy help in the deeper understanding of human nature and in the attainment of well-being?

We will not become young again, at least with current scientific knowledge, but we attempt to make the daily life and health of a person of a certain age as if they were much younger. If we truly succeed in this, it will be a tremendous achievement.
