100 Years of Solitude - The Big 5 Habits to live 100 years

1. Smoke-free - that includes vaping
2. Modest alcohol consumption:  Don't drink every day and not more than 2 drinks
3. Stay lean; Your height / your waist size > 2
4. Healthy diet:  Avoid highly processed food
5. Regular exercise - preferably HIIT and resistance exercise.

People who practiced all 5 of these live to around the age of 90 (Li, Yanping, et al. "Impact of healthy lifestyle factors on life expectancies in the US population." Circulation 138.4 (2018): 345-355).
