Do You Know Your Body Mass Index (BMI)?

Knowing your body mass index is an excellent way to begin understanding and assisting your body toward better health. This index (BMI) was designed to utilize a ratio of weight to height to determine health risks. BMI's that are above a certain number on the scale indicate probability of increased health risks.

A BMI over 24.9 signifies that a person is overweight, while a BMI over 30 indicates obesity. Research shows that being overweight has associated health risks such as heart disease, diabetes, and high blood pressure.

The higher the BMI, the greater the risk of health concerns.

A person in the normal weight range has a BMI of 19-24. Recent medical findings indicate that a low BMI (<19) carries increased health risk, too. Interestingly enough, there is a concern strong enough that consideration is being given to requiring runway models to have a BMI of at least 17 (which is still too low) in order to be allowed to model.

BMI scale <19 underweight 20-24.9 normal 25-29.9 overweight >30 obese

9th grade science projects get kids learning about science, yet they won't even realize they're "learning." Simple science projects are sometimes the best way to demonstrate scientific principles in a hands on way.

Astrobiologists at NASA and elsewhere are now seriously considering the possibility that life on Earth originated outside the planet and was brought into it by space debris impacting its surface over vast stretches of time. Do these space debris only contain ordinary matter? The scope of evolution will be considerably broadened if they also contain dark matter. Were the first cells a composite of dark and ordinary matter? Did dark matter bodies co-evolve with ordinary matter bodies?

Biologists are beginning to realize that co-operation was just as important as competition in the evolution of life's diversity and resilience. Every cell in the human body contains a mitochondrion which is thought to be a bacterial cell which invaded an early eukaryote. Instead of being digested, both cells tolerated each other and began to live with each other - a merger which provided synergies to both.

It seems saving the planet is a big deal, a world-wide goal, but, if we are truly going to save the planet we need to consider a few things first. For instance can 10 Billion people live on the surface of the planet and if so, will the planet sustain them all? How about 15 or 20 Billion? Well, at our current consumption levels most likely not. What if we reduce or consumption; can it be possible then?

Today, although it is somewhat uncommon many are living over 100-years of age. Each year more and more people make it to their centurion years. Have you ever wondered what the high-end of human life span might be in the future? Well, sorry for the delay in the reply to this question of your, I do believe it does deserve a legitimate answer. So, will it be possible for humans to live to be 250, 500 or even 1,000 years old?
