摘要:There is ample evidence that certain habits, life- styles and habitual or occasional behaviours have the potential of determining direct and/or indirect impact on health and on physical and mental wellbeing. For example, a healthy diet, regular and appropriate levels of physical activity, moderate alcohol consumption, and the abstinence from illegal drugs are considered healthy lifestyles that can predispose an individual to better health conditions. On the other hand, irregular eating behaviours, sedentary lifestyle, immoderate habits, and early and/or promiscuous sexual activity, are behaviours that can determine risks for an individual's health and life.
