Life expectancy for smokers |
Life expectancy for smokers In 2004, a study led by Richard Doll was published in the British Medical Journal, the first research that quantified the damage over the lifetime of a generation, based on a 50-year study of a group of almost 35,000 British doctors who smoked. The study found that almost half of persistent cigarette smokers were killed by their habit, and a quarter died before age 70. Further, those who quit by age 30 had the same life expectancy as a nonsmoker. Even quitting at age 50 saved six more years of life over those who continued smoking. At age 80, 65% of non-smokers were still alive, but only 32% of smokers. Fifty years before, Doll published in the same journal the first report of a study that linked cigarette smoking to lung cancer. |

Thomas Gold |
death Thomas Gold Died 22 Jun 2004 at age 84 (born 22 May 1920). quotes Austrian-British-American astronomer known for a steady-state theory of the universe, explaining pulsars, and naming the magnetosphere. In 1948, as a graduate student at Cambridge, he (together with Hermann Bondi and Fred Hoyle) proposed that, a continuous creation of matter in space is gradually forming new galaxies, maintaining the average number of galaxies in any part of the universe, despite its expansion. This is not accepted, as there is more evidence for the Big Bang theory. In 1967, Gold presented his theory on the nature of pulsars (objects in deep space that produce regularly pulsing radio waves). He suggested that they were rotating neutron stars - tiny, extraordinarily massive stars - which emit waves as they spin. |
