The growing number of dementia, depression, and cancer cases in today's world calls for new questions and new ways of thinking. Are there common underlying factors contributing to this twilight of the living on mental, emotional, and physical levels? What psychosomatic and culturally-psychosocial factors play a role? What does it mean to be truly alive? Modern egoism – where is it healthy and where does it become unhealthy? What does sympathy have to do with health? Through these and other questions, a completely new perspective on the dominant diseases of modernity can be developed, highlighting the central importance of human autonomy and independent thinking for future health.
