In the 1950's fashion models weighed 8 percent less than the
average woman. Today, models weigh 25 percent less.
2182/ Primitive folks
burned approximately 2900 calories per day hunting and gathering
food. Today the average American burns only 1800 calories.
2183/ If both of your
parents are obese, you have an eighty percent likelihood of
becoming obese. If 1 of your parents is obese, there is a
40 percent probability that you would be obese. If both of
your parents are lean however, there is only a 15 percent
chance that you will weigh more than 20 percent over your
ideal weight.
2184/ The menstrual cycle
is a physiological process which consumes calories. In the
post ovulatory phase (the two weeks before your menstrual
flow begins) your metabolic rate increases about 200-300 calories
per day. At menopause the loss of this function could cause
a weight gain of approximately 4-6 pounds a year.
2185/ Each pound of lean
tissue burns approximately 50 calories a day. A loss of just
half a pound of muscle or 25 calories expended daily, could
theoretically cause you to gain 2.6 pounds in a year.
2186/ One pound of fat
supplies the energy to walk nearly 30 miles.
2187/ The average female
has 27 billion fat cells. Obese women may have as many as
75 billion.
2188/ Resting heart rate
is very much genetic. Pro tennis player, Bjorn Borg had a
resting heart rate of 35 beats per minute. Borg was in fabulous
shape. But Olympic track star Jim Ryan, also in great shape,
had a resting heart rate of 75 beats per minute.
2189/ A survey of over
one-thousand inactive people who said they wanted to exercise
but didn't have the time found that eighty-four percent watched
an average of three hours of TV daily.
2190/ Exercise makes
you smarter. Alan Hartley, Ph.D., from Scripps College in
Claremont, California, studied three hundred adults aged fifty-five
to eighty-eight years old. Those who exercised had better
memories, reasoning abilities, and problem-solving skills.
2191/ A baseball pitcher
uses his legs to push off and gets 60 percent of his power
from his hips.
2192/ Americans gain
an average of eight pounds between Thanksgiving and New Years.
2193/ The parent of a
new baby loses between 450 and 700 hours of sleep in the first
year of a child's life.
2194/ Losing just one
hour of sleep every night for a week is equivalent to pulling
an all-nighter. Conversely, sleeping one hour longer per night
boosts a person's alertness by 25%
2195/ Research by the
Health and Safety Executive in the UK shows that nearly 150,000
workers have taken at least a month off sick because of stress-related
illness. Stress is now estimated to cost British industry
£370m a year.
2196/ In one study pilots
working on long flights were allowed a 40-minute nap, while
others got no nap. When compared to the flyers who got no
sleep, the nappers turned in a 34-percent higher performance
level and scored 100 percent better in terms of alertness.
2197/ $19.4 billion are
lost by US. industry every year due to premature employee
death.
2198/ Fatigue is a problem
throughout the rail industry. One study of train operators
found that 11 percent fell asleep on most or all night shifts,
with five percent reporting to have fallen asleep on most
or all early morning shifts, according to a 1993 study by
the National Commission on Sleep Disorders Research commissioned
for the U.S. Congress.
2199/ The military's
leading sleep expert, Colonel Gregory Belenky's high-tech
brain images show that sleep debt decreases the entire brain's
ability to function - most significantly impairing the areas
of the brain responsible for attention, complex planning,
complex mental operations, and judgement.
2200/ The Doppler effect
causes objects moving away to have their light spectrum red-shifted
while objects approaching have their light blue-shifted. This
really means that the wavelengths of light they radiate (or
reflect) are moved downward or upward on the frequency spectrum.
These measurements were the first clue that the universe is
expanding.
