Millionaires are Baby Boomers (or Older) For most Americans, incomes tend to rise with age and experience. Thus, it is not surprising that in 2009, 80 percent of millionaires were older than age 45 and close to half of all millionaires (46 percent) were older than age 55.
Theory. A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A theory is valid as long as there is no evidence to dispute it. Therefore, theories can be disproven.
Theory is different from a hypothesis. Hypothesis is merely an idea or a concept, which is not scientifically analyzed. These are the assumptions made by scientists before an investigation. However, once the hypotheses are analyzed and proved to be correct, they are recognized as theories.
