Drink coffee.
https://en.wikipedia.org/wiki/Coffee#Health_effectsIn 2012, the National Institutes of Health–AARP Diet and Health Study analysed the relationship between coffee drinking and mortality. They found that higher coffee consumption was associated with lower risk of death, and that those who drank any coffee lived longer than those who did not.
A 2014 meta-analysis found that coffee consumption (4 cups/day) was inversely associated with all-cause mortality (a 16% lower risk), as well as cardiovascular disease mortality specifically (a 21% lower risk from drinking 3 cups/day)
Additional meta-analysis studies corroborated these findings, showing that higher coffee consumption (2–4 cups per day) was associated with a reduced risk of death by all disease causes
