why do toenails get thick and hard

Q. Why do toenails thicken as we age but fingernails donБt? A. With age, there is a rapid decrease in the growth rate for both toenails and fingernails, said Dr. Richard K. Scher, head of the nail section at Weill Cornell Medical College. As a result, both kinds of nail thicken, because of the piling up of nail cells, called onychocytes. Fingernails do not thicken as much, however, because the decrease in their rate of growth is much smaller. And fingernails tend to be filed and buffed much more, which thins them. Other factors that can affect the rate of thickening include long-term trauma and impaired circulation. Feet, more than hands, are under constant stress, said Dr. Tzvi Bar-David, director of the podiatric surgery service at NewYork-Presbyterian/Columbia hospital. БWe walk many

 why do so many dogs get cancer

why do so many dogs get cancer

Could selection for large size in dogs be incidentally increasing the rates of cancer? Who knows, but it seems like something worth looking into. The other interesting thing about my graph of cancer mortality vs height is that there is a lot of scatter around the line. For breeds of a particular height, cancer mortality can vary two-fold or more. For instance, for their size, the Shih Tzu has an exceptionately low rate of cancer, while the cancer mortality of Welsh and Staffordshire Terriers is much higher than you would expect for their size. Among larger breeds, the Irish Water Spaniel, Bernese Mountain Dog, and Flat-coated Retriever are still stand-outs, while the cancer rates in the Pointer and Newfoundland are relatively low. Tossing all of these numbers onto a graph as we did at the

 why is my nose stuffy every morning

why is my nose stuffy every morning

Thanks all - we do have his 4-mo appointment tomorrow so I will ask the doc all of this. I'm inclined to think it's allergies because we have a number of family members (though not really me or DH) who have things like bad hay fever, etc. He sounded wheezy this morning, also. By a few hours into the morning, it was gone. -He is breastfed but not exclusively. About half bm and half formula. Could it be manifesting as an allergy to dairy now though he didn't seem to have it when he was littler? - He does eat in the middle of the night. We do an 11pm dream feed. He doesn't snuffle much before that, but I assume it just got worse as the night progressed. - I'll try the bedding thing this weekend to see if it helps. ...

why do we fold the american flag in a triangle

The custom of folding the United States flag into the shape of a triangle bestows unique honor and respect upon the flag. Although the origins of this custom are unknown, it is believed that that the practice was developed during World War I when patriotism was high and the flag was universally embraced as a national symbol. Many feel that it is reminiscent of the colonists who wore tri-corned hats during the Revolutionary War, of the three branches of our national government and of the three primary documents of our land: the Declaration of Independence, the Constitution, and the Bill of Rights. Did you know that at military funerals, the 21 gun salute stands for the sum of the numbers in the year 1776. Have you ever noticed how the honor guard pays meticulous attention to correctly

Is the start of Lent always on the same date? by licensed Actually, no. Since Lent is based on the date of Easter it changes every year.
