Does insulin regulate variability in life span?

If you want to live longer, the lifestyle of the elderly should be a model for you. You should be interested in why centenarians become centenarians and what they do to live so long.

Is it because they have low cholesterol?

Is it because they eat natural foods?

Is it because they exercise a lot and live a clean life?

Jean Calumet of France, is the oldest recorded person to have ever lived. In 2001 when he died, he was 122 years old. Well, if you want to learn about his lifestyle, you should know that he smoked all his life and drank.

As far as I know, there are three main studies that focus on the life and habits of centenarians around the world. All of them are trying to reveal the facts that would confer longevity among these people.

The conclusion of these large centuries-old studies is that there is hardly anything in common between all of them. There are centenarians with high cholesterol and low cholesterol, some smoke and some don’t, some exercise and some don’t, some drink and some are abstinent. Some are nice and quiet. On the contrary, some are unpleasant and tense.

But they still have one thing in common: low blood sugar, relatively for their age. They all have low triglycerides for their age. And they all have relatively low insulin.

Is this an opportunity to think that differences in life span are regulated by insulin?
