THE SPACESHIP EARTH

One of the interesting things to me about our spaceship is that it is a mechanical vehicle, just as is an automatic. If you own an automobile, you realize that you must put oil and gas into it, and you must put water in the radiator and take care of the car. You begin to develop quite a little thermodynamics sense. You know that you are either going to have to keep the machine in a good order or it's going to be in trouble and fail to function. We have not been seeing our spaceship earth as an integrally-designed machine which,to be persistently successful, must be comprehended and serviced in total.
   Quite clearly, all living beings are utterly helpless at the moment of birth. The human child stays helpless longer than the young of any other species. Apparently, it is part of the "invention" man that he is meant to be utterly helpless through certain anthropological phases and that, when he begins to be able to get on a little better, he is meant to discover some of the physical principles inherent in the universe as well as the many resources around him which will further multiply his knowledge.
    To comprehend this total scheme, we note that long ago, a man went through the woods, as you may have done, and I certainly have, trying to find the shortest way through the woods in a given direction. He found trees fallen across his path. He climbed over those criss-crossed trees and suddenly found himself poised on a tree that was slowly teetering. It happened to be lying across another great tree, and the other end of the tree on which he found himself teetering lay under a third great fallen tree. As he teetered, he saw the third tree third tree lifting. It seemed impossible to him. He went over and tried using his own muscles to lift that great tree. He couldn't budge it. Then he climbed back atop the first smaller tree,purposely teetering it, and sure enough it again elevated the larger tree. I'm certain that the first man who found such a tree thought that it was a magic tree, and may have dragged it home and erected it as man's first totem. It was probably a long time before he learned that any stout tree would do, and thus extracted the concept of leverage out of all his earlier accidental discoveries. Only as he learned to generalize fundamental principles of the physical universe did man learn to use his intellect effectively. By virtue of the leverage principles in gears, pulleys, transistors, and so forth, it is literally possible to do more with less in a multitude of physio-chemical ways.

Frequent masturbation

Frequent masturbation in young men is linked to higher risk of early prostate cancer , but it lowers prostate cancer risk for men in their 50s, a study shows. High levels of male sex hormones, or androgens, may increase a man's risk of prostate cancer . But different studies of this question, done in different ways, have reached different conclusions. To look at the question in a new way, a team of researchers  looked at whether men with more intense sex drives were at higher risk of prostate cancer.  About half the men got prostate cancer by age 60, and about half did not have cancer . The findings were surprising. Sexual intercourse did not affect prostate cancer risk. But frequent masturbation did -- in different ways, at different times of life. "Frequent masturbation during men's 20s and 30s increased their risk of prostate cancer. For men in their 20s, "frequent masturbation" was two to seven times per week. Compared to same-age men who reported mas...

Two flats in a one storey building at Nweke Nwobuchi Street, Umudioka village Awka, behind National secondary school was gutted by fire. The fire which alleged to be caused by a licked gas from a gas cooker, affected the top two flats destroying properties worth millions of naira. Speaking to newsmen at the scene, the owner of the building, Barrister Nnamdi Anagor, said that they were trying to fix the licking gas cylinder before the fire engulfed the building as they have earlier perceived the odour, and called on government and well to do citizens to come to their aid as they have lost their properties worth millions of naira. Barrister Anagor, disclosed that no life was lost to the incident but that one person sustained some injuries and has been hospitalized. Also speaking, a friend to the owner of the building, Mr. Maxwell Udechukwu, who alerted the Fire Service Agency through emergency number, thanked Governor Willie Maduabuchi Obiano for equipping the state's fire service...

HERNIA

Hernia occurs in an individual when part of the intestine pushes through the wall of the abdomen and appears as a bulge at the site. There are many sites where hernia can occur, although the commonly encountered type is that found in the groin. This type of hernia is known as femoral or inguinal hernia. Hernia may occur on the navel or near it. The hernia which occurs on the navel is called umbilical hernia, while that which occurs close to it is known as paraumbilical hernia. These two types of hernia are less common than the femoral type.   Groin hernia occurs more commonly in males, but can also occur in females in a few cases. In this kind of hernia, there is a weakness in the abdominal wall in the groin region about midway across the groin. It may appear on either side or, sometimes on both sides. A good sign is that swelling increases, initially it can be pushed back manually into the body. Later on, it gets bigger still and lies almost permanently outside the body, especi...
