Answer to Question 1

Most people attain their peak of physical and cognitive performance in their twenties.
Their memory and learning skills are at their best. Their sensory acuteness, muscle strength, reaction time, and cardiovascular fitness are also at their maximum. People perform their best on standard tests of intelligence in early adulthood. Subsequent declines in performance on intelligence tests may be due to a reduction in fluid intelligence (or mental flexibility) rather than crystallized intelligence (or accumulated knowledge). This latter type of intelligence may, in fact, increase with age. People also generally experience declines in memory functioning with age, but these declines are often not noticeable and/or do not affect general life functioning. People begin losing lean body tissue in early adulthood. Approximately 7 pounds of lean tissue is lost each decade. Between ages twenty and seventy, people lose as much as 30
percent of their muscle cells. In middle age, women's reproductive capability ends, as they no longer ovulate. This is referred to as menopause and generally occurs in the late forties or early fifties. In contrast, males remain fertile well into late adulthood; however, their level of testosterone gradually decreases with age.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
