Maybe they are right. Life expectancy in Europe is about 80 years old. I may be wrong but I suspect most people who are 80 years old now never exercised. They probably were physically active but didn't exercise in the modern sense of the term.

If you are reasonably active in your daily life and eat healthy food, I'm not sure exercising is such a necessity.

What you're missing from this observation is that exercise doesn't extend one's lifetime that much, but just improves the general quality of life, meaning that 80-year olds that are/were active in moderation now enjoy a bit better QOL [1].
