The average life span of men is 75 years and 80 for women. Although women's life span is growing shorter due to the fact they are smoking more, have taken on the role of man in some cases or taking on the position as the bread winner, entering into the work force, and becoming single parents more and more each day. The oldest documented person in the United States is a 114 year old woman in Ohio, who is a retired teacher.
Americans with a higher education live six years longer than high school dropouts. The elderly who attend worship weekly live longer than those who don't. Smoking typically cost you 10 years of your life or your life. Obesity cost an average of six years for men and seven for women.
Here are some of the risks of using tobacco. Biological dangers of tobacco radioactivity, we need to take into account the combined effect of various radioactive isotopes found in tobacco, the gaseous exchange in smokers' lungs (causing small particles to linger in the tissues), and radioactive "hot spots", such as the bronchial tree, where the concentration of radioactive elements may be one thousand times greater than in the lungs. Considering these factors, a person who smokes one and a half packs of cigarettes daily may receive as much as 60 milliards of radiation each day, 21.9 rads per year and 547.5 rads in twenty-five years, the equivalent of 547,500 chest xrays.
The chemical fertilizers used to grow tobacco contain calcium. Naturally occurring radium 226 is structurally similar to calcium and may fill its chemical bond, making these fertilizers radioactive. Because of wind direction in the United States, the East Coast, where most tobacco is grown, has high levels of airborne contaminants, including radioisotopes, For instance radon gas produced across the continent blows east and is concentrated in the East Coast. Air and soil radioactivity levels have also increased because of fallout fromnuclear testing during the 1950'S and 1960'S.
Lead 210, a decay product of daughter of radium 226 has a stro9ng tendency to attach to the tips of the fine hairs on tobacco leaves. As the tobacco leaves burn, lead 210 lodges in the lung tissue. Because lead 210 is not water soluble, it does not wash quickly out of the smoker's body. As it decays it exposes the body to carcinogenic alpha particles.
During its half life of 21.5 years, lead 210 further decays into another toxic isotope, polonium 210. Polonium 210 becomes volatile and dangerous at temperatures above 500 degrees centigrade, well below the temperature of a burning cigarette. It bonds strongly and rapidly to smoke particles. Polonium 210 has half-life of 138 days, ample time to shoot cancer-causing alpha radiation bullets at and into the bronchi and lungs. Researchers have confirmed that low doses of alpha radiation from polonium 210 can induce lung cancer in animals. The lung tissue, lymph nodes, and tumors of smokers contain unusual concentrations of the 210 radioisotopes.
