Live long and prosper

Calculating longevity is complex because multiple factors must be considered, such as a person’s age, past health issues, current health status, geography, and lifestyle. While genetics is the best predictor of a person’s ability to live a long life, adopting certain habits can help the body stay healthier longer. These include not smoking, maintaining a healthy body mass index, doing at least 30 minutes of daily moderate-to-vigorous activity, consuming only moderate amounts of alcohol if any, and following a heart-healthy diet.
