    AMERICA'S FIRST ASPHALT PAVEMENT
    July 29, 1870

    Was laid in Newark, N.J. Previously, coal tar was used for many pavements laid in the 1860s. The first recorded asphalt pavement in the U.S. was a sand mix placed in front of the City Hall in Newark, N.J., in 1870. Edmund J. DeSmedt, a Belgian chemist (who became the inspector of asphalt and cements for the District of Columbia) held a U.S. patent for this asphalt paving method, granted on 31 May 1867. In that century most roads, even in cities, were wide dirt pathways, severely affected by weather. Smooth surfaced asphalt roads originally were for the benefit of bicyclists. By 1904, only 141 miles were surfaced, but commonplace by 1916. Natural asphalt deposits were originally used, but almost all of the asphalt used commercially is now made from petroleum.

    THE FIRST IRON LUNG
    July 29, 1927 - United States

    (Electric Respirator) was installed at Bellevue hospital in New York for the post war polio epidemic. The first iron lung was developed at Harvard University by Phillip Drinker and Louis Agassiz Shaw built with two vacuum cleaners. The iron lung is a negative pressure machine which surrounds the patient's body except for the head, and alternates a negative atmospheric pressure with the ambient one, resulting in rhythmic expansion of the chest cage (and thus inhalation) in response to the negative extra thoracic pressure. During periods of ambient extrathoracic pressure, the lungs deflate. This type of machine is rarely used today.

    by Earth Day, Gaylord Nelson

    "...The wealth of the nation is its air, water, soil, forests, minerals, rivers, lakes, oceans, scenic beauty, wildlife habitats and biodiversity that'as all there is. That'as the whole economy.

  • 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...."

    Steve Jobs' annual salary was $1, just enough to keep company health benefits. More vehicles
    about Stolen On New Year's

    More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)

ARTICLE CONTENT :

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.
