  • why does hair and nails grow after death

    Your hearts stops, your blood goes cold and your limbs stiffen. Yet amidst the signs that you are no more, your fingernails continue to lengthen and your hair grows or so we re told. The young narrator in Erich Maria Remarque s novel All Quiet on the Western Front imagines the nails of a friend who has died of gangrene continuing to grow into corkscrews as the hair on his decaying skull lengthens like grass in good soil. It s an idea that s not pleasant, yet seems to endure. Is it true, though? Not surprisingly there haven t been many systematic studies measuring daily changes in fingernail and hair length in the dead. For hints we can turn to historical anecdotes and descriptions provided by medical students working with cadavers. Transplant surgeons are also experienced in calculating the length of time the different kinds of cells continue to function beyond death. Different cells die at different rates.

    why do we see colors when our eyes are closed

    You settle in for bed. You close your eyes and right before you fall asleep, you notice something; a twinkling, swirling pattern of stars and colors producing a make-shift light show on the inside of your closed eyelids. Many people who have seen this visual phenomenon think it is an light-induced afterimage of what they had seen before they closed their eyes but an afterimage may only be part of what they are seeing. The real reason we are treated to this fuzzy fireworks display behind closed lids has to do with phosphenes! They are thought to be caused by the inherent electrical charges the retina produces even when it is in its "resting state" and not taking in a ton of information and light like it does when our eyes are open. One can relate this analogy to an old fashioned television set. When its on and on the right channel, you see colors, pictures and images similar to what our retinas allow us to see when our eyes are open. However, unlike a TV set, our retinas can not be turned off. Even when we close our eyes, they are active.

    why does diabetes make you lose weight

    Diabetes mellitus is a metabolic disorder where the body does not use energy properly. One of the symptoms of diabetes is sudden and unexplained weight loss. Excessive hunger and thirst are two other symptoms, and patients with untreated diabetes may find themselves losing weight even as they are eating and drinking more than usual. There are several reasons why people with diabetes lose weight, but to better understand why weight loss occurs, you need to explore how diabetes affects the body. Under normal circumstances, your body converts food into sugar during the digestive process. The sugar enters your bloodstream and the pancreas, a small organ behind the liver, release a chemical known as insulin. Insulin tells all the cells in the body to take sugar from the blood and convert it to energy, which the cells use as fuel. There are two types of diabetes mellitus -- type 1 and type 2. With type 1 diabetes, the body either does not make insulin, or it does not make enough, and the cells never get the chemical signal to absorb sugar from the blood. With type 2 diabetes, the body makes insulin but the cells do not respond to the chemical signals, or they respond incorrectly.

    why does ice melt at room temperature

    Why does ice melt faster in water( at room temp. ) than in air? Asked by:
    Vishal. N. Buxani Keep in mind that temperature is the average kinetic energy of the particles in a substance, whereas heat is the total energy of all the particles. The air and water may have particles moving the same speeds, but the water has more heat because there are more particles. Picture it this way. The ice melts as fast moving particles slam into the slow moving ice particles. As in any collision, some of the energy is transferred to the ice particle, and with its new energy it can break out of the crystal and flow as a liquid water molecule.

    why do you get wisdom teeth pulled

    Your dentist says you need to have your taken out. But they donБt hurt, you say, so why remove them? These days, oral surgery to remove
    is a standard practice -- almost a rite of passage for young adults. It's not always necessary, though. Still, just because your wisdom teeth arenБt a source of pain doesnБt mean thereБs nothing wrong. The could be stuck, or impacted. That means they canБt break through your jaw and into your. Maybe your is too small to make room for them, or the teeth could be growing at an angle to other teeth. They can damage the next door if they push up against it. Some dentists take out healthy molars to prevent problems later on. As you age, the bones in your get harder. That makes your teeth tougher to remove. If you wait, you could have problems after surgery that range from heavy bleeding and fractured teeth to severe numbness and minor loss of movement in your jaw. These troubles could last a few days or a lifetime. When Is Removal Needed? When wisdom teeth cause problems, or X-rays show they might down the line, they need to come out.

    why do we test water for domestic use

    БI should get this water tested some time. Б ThatБs something most farmers and owners of tanks, bores and swimming pools will have thought or said at times. Unfortunately, not everyone acts on it. We hope this page helps convince you of the need to get your (non-town) water tested now. Good reasons to have your water tested 1. Human health Б safe drinking water
    Nothing is more important than your health and that of your family and visitors. If you use your own water source for drinking, you need to have it tested every so often. You donБt want to be responsible for anyone getting sick by drinking your water. Your drinking water should contain no harmful concentrations of chemicals or pathogens and ideally it should be aesthetically pleasing in regard to appearance, taste and odour. At RWL, we measure your sample of drinking water against the Australian Drinking Water Guidelines to assess the safety and aesthetic quality of the water. 2. Stock health Wondering why your stock is looking poor or malnourished? ItБs important to get the stock water checked to ensure it is suitable. The water may have an unacceptable chemical composition (e. g. too acidic or alkaline or high concentrations of certain elements) or be physically unsuitable with the presence of toxic blue-green algae species. 3.
