Jeanne Calment is the oldest verified human in history, living 122 years and 164 days. What makes her story fascinating is that she smoked, drank wine, and ate chocolate regularly—things normally considered unhealthy. So what explains her extreme longevity? Doctors and researchers say it wasn’t those habits, but a combination of deeper factors.
1. Exceptional genetics 🧬
Many longevity researchers believe genetics played the biggest role.
- Several members of her family also lived unusually long lives.
- Scientists studying her case concluded her lifespan likely resulted from strong genetic inheritance plus luck. (unige.ch)
In other words, she may have had genes that protected her body from aging and disease longer than most people.
2. Low stress and a relaxed attitude 😌
Calment herself often said her secret was not worrying.
“If you can’t do anything about it, don’t worry about it.”
Researchers think her positive personality and low stress levels helped protect her heart and overall health. (Why Dont You Try This?)
She lived a comfortable life, didn’t work demanding jobs, and maintained a cheerful outlook.
3. Staying active—even in very old age 🚶♀️
Even after turning 100, she stayed surprisingly active.
- She did daily seated exercises and stretching.
- She remained mobile and mentally sharp well into her 110s. (The Times of India)
Regular movement is strongly linked to longer life.
4. Mediterranean-style habits 🍷🫒
Although she smoked and drank wine, some of her habits were actually health-promoting:
- She used and consumed a lot of olive oil.
- She enjoyed dark chocolate.
- She drank small amounts of wine rather than heavy alcohol use. (Perpusnas)
These foods contain antioxidants often associated with the Mediterranean diet, which is linked to longevity.
5. Moderation (even with “bad” habits)
She smoked only after meals and drank small glasses of port wine, not heavy quantities. (The Times of India)
Doctors say this matters because extreme habits are usually what cause the most damage.
✅ The key takeaway doctors emphasize:
Her smoking and wine were not the reason she lived to 122. Instead, her longevity likely came from:
- strong genetics
- low stress
- staying mentally and physically active
- a balanced lifestyle
Her case is considered an extraordinary exception, not a lifestyle to copy.
