Of course, the things that reduce the quality of life the most are health problems. But apart from these, society, social pressure, lack of respect, and empathy reduce the quality of life. No matter how visionary or qualified a person is, or how high a quality of life they want, social pressure can be a barrier in front of that person. A person whose decisions are not respected has less chance of living a quality life. Or that's what I'm thinking right now because I'm angry because of the disrespectful people around me who lack empathy.
