Show YOUR SNEEZE MAY NOT BE FROM COLD Draft May Have Nothing to Do With the Matter Million Particles. WHEN you sneeze it Is not always al-ways a sign you are taking cold. That is the opiulou of physicians working- on putdic health problems in the last tew years. Most men and women when they feel that tickling In the nose or throat Immediately Im-mediately look for the nearest door or window, convinced that they are sitting sit-ting in a draft. However, the draft, if there is one, I may have nothing to do with the mat-' mat-' ter at all, physicians eay. The unhappy un-happy one merely has Inhaled a few million or so dust particles. That may be true particularly of our cities where enough dust floats In the atmosphere in one year to build a cone-shapod mountain 1.500 feet high, with a live-mile diameter. Some statistician has figured it out that if all the dust that hovers above American cities were gatlu-red in one place, say Manhattan Islund, that dust would be piled up on the streets of Manhattan to the depth of 21 feet. But one is likely to sneeze while I walking along a country road, though uot quite as likely as In the city. Here the dust that is raised usually comes from dirt or gravel roads. There Is. however, less likelihood of this today than ever before as highway nfiiciakj now have at their command many methods for "binding" the top cover, particularly the use of such chemicals as calcium chloride, considered by en- gineers the best of dust layers. |
