Life is scientifically defined as biological processes that distinguish living entities from inanimate objects. The criteria for what constitutes life can sometimes be ambiguous and may include or exclude viruses, viroids or hypothetical artificial life. Different cultures have varying philosophical and religious perspectives on the meaning and purpose of life. Personally, the author believes life is about embracing one's sense of responsibility, including responsibility to God, to oneself and family, and to other creatures. How well one balances these responsibilities determines the quality of their life experience.
