It's all probability, not guarantees.

Leading a healthy lifestyle increases your chances, eating like a pig decreases them.

Looking at the outliers and saying "See?! It's all a lie!" is like looking at a lottery winner and concluding that lottery tickets are a sound investment.

What's interesting is the people who are "unfit" and especially obese seem to fair the worst.

Most of the people I spoke of, drank and smoked a lot, but also active to very active, and exercised regularly even in their 80s. Swimming, walking, playing tennis, yard work, gardening. They all seemed to share these things in common.

Being Obese and sedentary seems to be a dangerous undertaking.

I think you may have hit on something there.

Grandpa gave up cigarettes at age 75 or so. Only made it another ten years.

Could outwork teenage me at age 75.
