"Health is correlated to people’s socioeconomic status (SES) and lifestyle.[...] Lifestyle had significant positive effects on both physical and psychological health. In addition, lifestyle mediated the relationship between SES and health. This research is helpful in gaining a better understanding of the relationship and mediating mechanism between SES, lifestyle, and health. It is recommended that research with longitudinal design and comprehensive indicators be undertaken in the future."

"A wealth of research shows that how much of it we possess dramatically affects not only our happiness and wellbeing but also our physical health – and without sufficient status, we become more ill, and live shorter lives. It’s an unconscious obsession that drives the best and worst of us: our innovation, arts and civilisation as well as our murders, wars and genocides."
