It's no secret that a healthy lifestyle can prolong one's life، but Harvard scientists dove deeper and outlined how we can add a decade or more just by following some simple habits، as Technical Times said. Lifestyle choices are a huge factor in one's life expectancy. Poor health habits can chop years off one's life، while healthy ones can add 10 years or more، but it takes will and determination. According to a new study from the Harvard T.H. Chan School of Public Health، there are five simple healthy habits that can do wonders for one's life expectancy. First of all، sedentary lifestyles and junk food must be eliminated. It may not be easy، but being a couch potato and eating unhealthy food can seriously damage your health. To prolong your life expectancy، the study suggests adopting a healthy diet، maintaining a healthy weight، exercising for at least 30 minutes every day، drinking alcohol only in moderation، and not smoking at all. These habits may seem simple and quite obvious، but they're not always easy to follow. The recommended body weight and body mass index or BMI can pose challenges to many people، especially Americans. At the same time، cutting out junk food، smoking، and exercising daily could also be challenging. For most، drinking in moderation might be the easiest habit to maintain.
