Bone has been described as an engineering masterpiece of tensile, compressive and elastic strength.
The human skeleton consists of approximately 206 bones and 68 joints. The largest bone is the femur, or thighbone; the smallest is the stapes, a bone inside your ear.
As skilled gymnasts clearly demonstrate, bones, muscles, cartilage, and joints can give a healthy body an astonishing degree of flexibility and range of movement.
The thumb alone would convince anyone that the architect of our body [whoever that may be to each one of us].
Bones can also take an incredible pounding. They are constructed in exactly the same way that reinforced concrete is constructed.
The steel of reinforced concrete provides the tensile strength, while the cement, sand, and rock provide the compressional strength.
However, the compression strength of bone is greater than that of even the best reinforced concrete. We only wish we could mimic it” said Robert o. Ritchie, a professor of materials science at the University of California, Berkeley, U.S.A.
Unlike concrete, bone is an essential part of countless living organisms. And it is dynamic. It is able to repair itself, respond to hormones that affect its growth and development, and even play a key role in the manufacture of blood cells.
Also, like muscle, it slowly grows stronger as the load on it increases. Hence, athletes have heavier bones than so-called couch potatoes.
A fatty diet can clog your brain as well as your coronary arteries. To understand the effects of a high-fat diet on the brain, researchers in Canada; fed one-month-old rats a diet rich in either animal or vegetable fat until they were four months old.
A control group was fed a low-fat diet. Both groups were then given learning tasks. The results? The rats on the two high-fat diets performed much more poorly than the lean rats.
Researcher Gordon Winocur said: high-fat diets impair performance on virtually all our measures. It’s remarkable how impaired these animals are. According to the report, the researchers feel that;
Fat prevents the brain from taking up glucose, possibly by interfering with the action of insulin, which helps regulate blood sugar level.
