When things in your life seem almost too much to handle; when 24 hours in a day are not enough remember THE MAYONNAISE JAR AND TWO CUPS OF COFFEE: A professor stood before his philosophy class and had some items in front of him. When the class began, wordlessly, he picked up a very large and empty mayonnaise jar and proceeded to fill it with golf balls. He then asked the students if the jar was full. They agreed that it was. The professor then picked up a box of pebbles and poured them into the jar. He shook the jar lightly. The pebbles rolled into the open areas between the golf balls. He then asked the students again if the jar was full. They agreed it was. The professor next picked up a box of sand and poured it into the jar. Of course, the sand filled up everything else. He asked once more if the jar was full. The students responded with a unanimous "yes." The professor then produced two cups of coffee from under the table and poured the entire contents into the jar, effectively filling the empty space between the sand. The students laughed. "Now," said the professor, as the laughter subsided, "I want you to recognize that this jar represents your life. The golf balls are the important things - God, family, children, health, friends, and favorite passions -- things that if everything else was lost and only they remained, your life would still be full. The pebbles are the other things that matter like your job, house, and car. The sand is everything else -- the small stuff. "If you put the sand into the jar first," he continued, "there is no room for the pebbles or the golf balls. The same goes for life. If you spend all your time and energy on the small stuff, you will never have room for the things that are important to you. So...Pay attention to the things that are critical to your happiness. Play With your children. Take time to get medical checkups. Take your partner out to dinner. Play another 18. There will always be time to clean the house and fix the disposal. "Take care of the golf! balls first -- the things that really matter. Set your priorities. The rest is just sand." One of the students raised her hand and inquired what the coffee represented. The professor smiled. "I'm glad you asked. It just goes to show you that no matter how full your life may seem, there's always room for a couple of cups of coffee with a friend."

Dear Friends:
You probably never thought of this, but women's shelters in the U.S. go through thousands of tampons and pads monthly. Assistance agencies generally help with expenses of "everyday" necessities such as toilet paper, diapers, and clothing, but one of the most BASIC needs is overlooked - feminine hygiene products. (Who is at the helm of the funding assistance agencies!?) Seventh Generation, a green paper products and cleaning products company, has a do-good attitude and will donate a box of sanitary products to a women's shelter in your chosen state - just for clicking the link. Talk about easy (literally takes less than 1 minute and they ask nothing of you). And, yes, it is Legitimate! http://www.tampontification.com/donate.php |
Water intoxication—not a runner's high - Brief Article
Running & FitNews, August, 2000
If you run for a very long time--racing or
training--water may not be your best choice for
avoiding dehydration, especially in hot weather.
Drinking water without electrolytes can lead to
dilution of normal blood sodium concentration.
Without the proper amount of sodium, as the blood
system absorbs extra water, excess fluid can build
up in the brain and lungs. The condition is
hyponatremia and the consequences can be fatal
(see Running & FitNews, September, 1999). Known
fondly as "water intoxication," runners can
develop brain swelling and serious amounts of
fluid accumulation in the lungs. When this
happens, oxygen is not transported into the
bloodstream efficiently, and you can become short
of breath, nauseated, and disoriented. The problem
is more common in female runners.
Researchers from Baylor College of Medicine in
Houston studied the development and treatment of
marathon and ultradistance runners with pulmonary
edema (essentially dry land drowning as the lungs
fill with fluid). Seven fit and previously healthy
marathoners, ranging in age from 29 to 46, became
ill with respiratory distress, coughing pink
frothy sputum, low oxygen levels, low serum
sodium, and brain swelling. Five were female. The
runners received treatment with intravenous fluids
containing large amounts of sodium. One woman
died. Four additional female runners who competed
in the Houston Marathon this year also had the
syndrome.
Running shorter distances (an hour or less) does
not pose the same risks and water is fine for
rehydration. But ultradistance and marathon
running in which exertion exceeds four hours can
set the stage for hyponatremia. Sweating causes a
loss of water and sodium, which reduces the total
blood volume. When you drink water it further
dilutes the blood. As you begin to feel sick, your
natural response may be to drink more water, which
can cause your sodium level to become extremely
low.
As hyponatremia develops, the symptoms are easy to
confuse with other conditions like heart attack or
ironically, dehydration or heat stroke. The
cruelest irony of all is that the response to
these conditions may be to give more water. Making
this misdiagnosis, and giving low sodium fluids,
can be a fatal mistake. The lesson for each
runner--if you are running an hour or more,
replace fluids with a sports drink that includes
electrolytes. If your exertion lasts longer than
four hours, you need to increase your intake of
salt beyond that found in most sport drinks.
Although your body needs water in order to avoid
dehydration, if your exertion is prolonged, water
must be balanced with sodium. (Annals of Internal
Medicine, 2000, Vol. 132, No. 9, pp. 711-714)
* Don't drink more water than you sweat--compulsive water drinkers can start a race with a low sodium level.
* When sweating a lot, choose sport drinks (that contain some sodium) over water (which has none).
* Don't overhydrate in the days before the race. You can't stock up on fluids like a camel.
* Eat a relatively salty diet in the days before the race.
* Eat some pretzels in the last half of the race.
