Lifeology means: To form generalizations about the life of people, it is necessary to study their lives and learn from them. Traditional biography is different from lifeology because it only examines famous, wealthy and successful individuals. Lifeology however studies all successful and unsuccessful people to find out about humankind’s personal lives. Although it is still a young science, this field has a lot to offer in terms of understanding life and ways to improve it. (in Community Dictionary, added by Feliciano Carmona)
