Jack LaLanne, exercise guru and healthy-eating aficionado lived to 96. His brother Norman, who did none of the things his brother did to the same level, lived to either 96 or 97.

On a related note, I love posting this study https://jamanetwork.com/journals/jamanetworkopen/fullarticle...
Look at Figure 2C in particular. The hazard ratio of smoking is 1.41. The hazard ratio between "Low" (<25th percentile) and "Below Average" (25th-49th percentile) cardiovascular health is 1.95.
In other words, it is better to be a smoker than in the lower 25% of non-exercisers. By far. It's not even close.
