If you are a teenager when you read this, you might not be very excited by such a title. And yet the younger you are the most interested you should be in longevity. That's because you have more chances to improve it than older people. To me the most important aspect of longevity is not the quantity but the quality of the years we can all add to our lives, specially towards the end.

I like this idea that chronic stress is of a different nature than occasional ones. Our body is made to fight or flight in case of instant serious danger like a tiger attack. But how does it react to the constant relentless small aggressions of modern life?

There are all sorts of myths about cholesterol. Some promoted by the pharmaceutical industry to sell their products. Some as a result of ignorance. From time to time it seems a good idea to check what we really know about this important fat which is a part of the human body.

Could common sense slowly reach the medical world? You might think so when you read this article from the Courier Journal.

It seems to be. "Experts opine that your daily laugh quota total should equal at least 15 chuckles a day, or you are under laughed!" So says this article in the Times of India.

I never met Noemi Anderson and probably never will. But I wish I had her sense of humor and her zen like approach to life at 110 years of age.

Why don't these super centenarians build a club to share with the rest of us their tips and secrets? One of Noemi's seems to be simply walking a lot, but there must be others. What are they?

Today I added a "Creativity News" Category. Rereading pages of the "World is Flat" of Thomas Friedman I realized how different the world of our ancestors was from the one we live in. For centuries things did not change or changed very slowly. If your parents were farmers you generally ended up your life as a farmer.

Kudos to Texas Instruments for its Wellness Program! First it seems to work. In addition the use of a software tool easily ingrains new healthy habits.

One of the benefits is to make people aware of their life-style's destructive habits and to help them acquire new health promoting ones. Not a small advantage in today's world where everything seems to be made to promote junk food and irresponsible attitude.

This BBC article does not really answer the question: Exercise, yes but how much? And it is true that there is no such thing as one-size-fits-all for exercise. It is my experience however that what really matters is to create the habit of regular exercise whatever happens. Good weather, bad weather, good mood, bad mood.

Until we really understand what is going on with cancer why not try good old common sense? Like prevention for instance. When I see the millions that are spent all over the world to cure the multiple forms of cancer, I can't believe we truly know the reasons this horrible disease still develop.
