Who
is physically fit? Physical
fitness generally refers to cardiovascular fitness, or how effectively
the heart and lungs supply oxygen to the muscles. While such fitness
allows you exercise longer, its most important benefit is a reduced
risk of major diseases such as coronary heart disease and stroke.
Researchers evaluate cardiovascular fitness by measuring the heart
rate during and after treadmill exercise. As a self-test, see how
fast you can walk a 400m without getting winded. If it takes you
more than 5 minutes at a comfortable pace, you may want to pursue
some sort of cardiovascular exercise program.

Fidgeting
may burn more calories than you think. The
calories used by low-grade physical activities may help prevent
weight gain, according to recent studies from the Mayo Clinic
in Rochester, Minn. Researchers measured the calories burned when
volunteers tapped their hands and feet, or swung their arms and
legs while sitting. Standing fidgets included ambling around,
and pretending to change a video, fold sheets, or interact with
pets.
In a previous study, researchers had found that increasing non-exercise
activities helped sedentary adults resist weight gain. They showed
that fidgeting activities can substantially increase calories
burned compared with motionless sitting or standing.

Anger
can kill you. Anger
tends to speed up the heart, raise blood pressure, and narrow
the blood vessels. In theory, those changes can eventually damage
the arteries. And once they're damaged, a bout of rage can trigger
a heart attack. Numerous studies have indeed shown that hostile
people who get angry more often, more intensely, and for longer
periods than others - are anywhere from 50 to 300 percent more
likely to develop coronary disease or have a heart attack. So
the next time you feel like "blowing your top", relax
and think about you health.
