    EDISON'S PHONOGRAPH
    November 21, 1877 - New York City, U.S.A.

    Thomas Edison announced his invention of his "talking machine" - the tin-foil cylinder recorder that preceeded the phonograph. He appears to have envisioned it as a business dictation machine. In Sep 1877, he wrote that its purpose was "to record automatically the speech of a very rapid speaker upon paper; from which he reproduces the same Speech immediately or years afterwards preserving the characteristics of the speakers voice so that persons familiar with it would at once recognize it." The indented tin foil, however, would survive only a few playings. By the first public showing of a phonograph, which took place in New York City in early Feb 1878, its practical applications had not yet been realized.

    WIRELESS TELEPHONE AT WHITE HOUSE
    November 21, 1919 - White House, U.S.A.

    President Wilson used a radio telephone set up on the south portico of the White House to direct the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. His telephoned directions went direct to the flight commander in the air. The instrument was similar to those used by American aviators in France in the latter part of World War I. Col. C. C. Culver actively developed the equipment. He began the project in Aug 1910. No new invention was needed, only adaptation and adjustment of existing techniques. By Aug 1916, he was able to send a radio telegraph signal from a plane. Enlisting expert help from the telephone companies, by Oct 1917, voice messages could be send between a plane and the ground. The system was put into service for military wartime use.

  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."
  • Until a man duplicates a blade of grass
    by Earth Day, Thomas Alva Edison Inventor

    "...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."

Hardly anybody now can find sufficient time to take of their well-being properly, as we get caught up in day-to-day routine. Yet, taking care of ourselves does not need much time and effort. It starts with a healthy well-balanced diet and regular physical exercise and you will not only feel better, but look better, as well. It is never too late to begin a healthier life-style, regardless of age and gender. Now and again we suffer from different diseases, thus there is no excuse for being health unconscious.

Your well-being is immensely influenced by the life-style you lead. Also, lifestyle determines medical conditions you suffer from and your life expectancy. Smoking, alcoholism, bad eating habits, lack of exercise bring on life-style related health problems. Cardiac diseases, corpulence, tumours are the main life-style related medical conditions. The preponderance of these health determinants is thought to lead to a generation of children and young people who will suffer from coronary diseases and other health problems at an earlier age.

Proper dietary changes improve health and considerably reduce the risk of chronic health problems. A nutritious well-balanced low-fat diet high in fruits and vegetables will help you feel and look healthy. Conscious changes in food habits should be made by people. Dietary changes in lifestyle have durable benefits for your well-being and one of the primary steps to begin with.

Corpulence is the main cause of health problems, such as cardiac diseases, type 2 diabetes and hypertension. Watching one's weight is very important and overweight people should make a conscious effort to lose weight. Introducing exercise into your lifestyle is of importance in maintaining healthy weight, improving heart health and lowering other risks.

Lack of physical activity is an inactive lifestyle and a speedily growing medical concern. Physical inactivity is a major risk to both physical and mental health. Recent studies have shown that physical inactivity is worse than being corpulent. It brings on an increasing rate of chronic diseases, not just in the elderly but in youngsters and adults. Being physical inactive, in the long run, minimizes your self-esteem and adversely affects your outlook on life. Leading a healthy life-style can improve your health and life. If you already know, then it is high time you made some serious changes in lifestyle.
