Physical activity patterns during the young adult years are likely to
be important influences on habitual physical activity during overall adult
life and, consequently, have significant implications for long-term health
outcomes. The potential reach and impact of college physical education on
the promotion of physical activity to a large segment of the American
population has been largely unrecognized. Over the last generation, many
colleges and universities have reduced or eliminated their physical
education requirements. Nonetheless, physical education can make important
contributions in the primary prevention of inactivity-related chronic
diseases and to the general education of the college student. Awareness and
advocacy are needed to strengthen college physical education programs.

....from Phil Sparling, Ph. D "College Physical Education - An Unrecognized
Agent of Change in Combating Inactivity Related Diseases."

The point here is that in 2005 diseases directly linked to inactivity will
kill more adults than smoking related diseases. Inactivity diseases are
being given a new name by the CDC "Sedentary Death Syndrome"

Get Off Your Fatty Acids - Go Play. The recommendation is 30 minutes of
moderate physical activity every day.
