ABSTRACT
Health and longevity are determined by many factors including genetics, nutrition, family environment, work environments, the distribution of wealth within countries, and the prevalence of stressful working environments (cf. [1,2]). Within this context, individual behavior patterns have an important impact on individual and public health. The Alameda County study followed 7000 people over 10 years and showed that sleep, exercise, drinking alcohol, and eating habits predicted mortality [3]. Similarly, Khaw et al. [4] found that controlling for age, gender, body mass index, and socioeconomic status, a group of 20,000 people, those who smoked and consumed more than moderate quantities of alcohol, were not physically active, and did not eat ve portions of fruits and vegetables a day, were more than four times more likely to have died than those not engaging in these four behavior patterns-over an 11 year observation period.
