Everyone knows that exercise is good for you, but here's an article that confirms if you exercise and lower your body fat, you not only lower your blood pressure, but you also reduce your risk of getting heart disease and diabetes. So exercise to live longer -- in other words, "Here's WHY you should exercise!" Dr. Rehert
Exercise Away Risk of Early Death
By Jeanie Lerche Davis -- Reviewed By Brunilda Nazario, MD
Dec. 29, 2004 - Want to live longer? Start exercising regularly and melt fat away. An hour of exercise can improve fitness, but losing body fat staves off the deadly "metabolic syndrome," according to new research.
High blood pressure, high cholesterol, elevated blood sugar, and excess belly fat are the mix of risk factors known as "metabolic syndrome." This cluster of risk factors increases your risk for heart disease, diabetes, and early death.
Exercise has been recommended to reduce a variety of these risk factors. Studies have shown that exercise works to reduce body fat, especially fat around the waistline. It also helps with heart disease factors like high blood pressure and high cholesterol. But this current study looks at the broader effects of regular exercise on this mix.
The study involved 115 people aged 55 to 75 -- the typical older American with mild high blood pressure, many of whom were overweight.
Half were assigned a six-month moderate-intensity exercise program about one hour long, three days a week. However, they stuck with their regular eating habits.
The exercisers' risk factors improved, whereas those of the comparison (non-exercise) group didn't, he says. The exercisers lost more body and waistline fat and gained more muscle than the comparison group. Heart disease risk factors, like high blood pressure and cholesterol, also improved more in the exercisers.
"Older people can benefit greatly from exercise, especially to reduce their risk for developing the metabolic syndrome," says Stewart in a news release. "Our results show that this population can be motivated to follow through with a moderate exercise program, and for some risk factors, such as abdominal fat, exercise can be as effective as what is accomplished today with drugs."
Other examples of moderate-intensity activities include walking briskly, recreational swimming, or bicycling 5-9 miles per hour on level terrain.
For the men in the audience, if you use a laptop computer on your "lap," be careful -- you're at risk for the following syndrome:
Sperm does not compute
BY Corky Siemaszko -- DAILY NEWS
Want to be a dad? Keep the laptop off your lap. Scientists from SUNY Stony Brook have discovered that heat generated by laptop computers can potentially affect sperm quality and quantity.
"The body needs to maintain a proper testicular temperature for normal sperm production," said lead researcher Dr. Yefim Sheynkin. "Portable computers in a laptop position produce scrotal hyperthermia." That's a fancy way of saying toasted testicles.
To see how those oven-like conditions might affect a man's ability to produce a bun in the oven, researchers tested 29 volunteers ages 21 to 35. They discovered that, after an hour of computer surfing on their laps, testicular temperature jumped by 3.6 degrees. Any increase of 2 or more degrees above the average scrotal temperature of 94 to 96 degrees can cause changes in sperm count, Sheynkin said.
And finally we all know of the monumental suffering and needs in SE Asia. If anyone of you would like to help the Tsunami-Earthquake victims, you can easily contribute on-line through many relief agencies. Here I've given you links to two of the best: "Save the Children" and the "American Red Cross." All you need is an amount and your credit card . . . Go ahead, It'll make you feel good.
