- The French smoke like chimneys
- Drink some form of alcohol daily
- Are dedicated carnivores (vegetarians are rare)
I come here a few months a year (south of France) and it always amazes me how healthy everyone appears to be despite the excess of "sin" the French revel in.
Lifestyle obviously comes into play in terms of longevity (I believe the world's oldest woman was French and she smoked moderately into her 100s). In other words, the phrase, "work before pleasure", very likely did not originate in France.
