e share 98.4 percent of our DNA with chimpanzees—and 70 percent with slugs.
It takes an interaction of 72 different muscles to produce human speech.
Diabetes is a silent epidemic and according to The World Health Organization (WHO), there are 246 million people in the world living with diabetes. That is almost 6% of the world's adult population.
When you sleep, you grow by about 8mm (0.3in). The next day you shrink back to your former height. This is because your cartilage discs squeeze together like sponges by gravity when you stand or sit.
Some herbal supplements – from the popular St John's Wort and ginkgo biloba to garlic, ginger, ginseng and feverfew – can cause increased bleeding during surgery, warn surgeons. It may be wise to stop taking all medication, including herbal supplements, at least two weeks before surgery, and inform your surgeon about your herbal use.
Have a pap smear once a year. Cervical cancer kills 200 000 women a year and it’s the most prevalent form of cancer among black women, affecting more than 30 percent. But the chances of surviving this cancer are nearly 100 percent if it’s detected early.
Get your daily calcium by taking a supplement, drinking milk or eating yoghurt. It’ll keep your bones strong. Remember that your bone density declines after the age of 30. You need at least 200 milligrams daily, which you should combine with magnesium, or it simply won’t be absorbed.
In one square inch of our hand, we have nine feet of blood vessels, 600 pain sensors, 9000 nerve endings, 36 heat sensors and 75 pressure sensors.
The soles of your feet contain more sweat glands—and pressure-sensitive nerve endings--per square inch than any other part of your body.
Your stomach lining replaces itself every three to four days. If it did not do this your stomach would digest itself. If you have ever had a stomach ulcer you will know how painful this is.
MATTERS OF THE HEART
The average heart weighs between 7 and 15 ounces (about what an apple weighs) and is a bit larger than your fist.
It pumps out 2 ounces of blood at every heartbeat, totaling over 2,500 gallons every day.
Your heart never stops. It begins beating about 22 days after conception and ends when you do. At the end of a long life, the heart can beat up to 3.5 billion times.
A man’s beats at 70 beats per minute while a woman’s beats at 78 per minute.
Pollution hurts more than your lungs
When pollutants are inhaled, they trigger an increase in "reactive oxygen species," which are superoxiding molecules that damage cells, cause inflammation in the lungs, and spark a cascade of harmful effects in the heart and cardiovascular system. Hearts exposed to pollution are also at higher risk for arrhythmias.
A sneeze stops the heart? That, say heart experts, is simply a myth.
Notice when people say the Pledge of Allegiance, that they place their hands slightly to the left on the chest? That's because most people think their hearts are on the left sides. The truth is your heart is dead center in the middle of your chest. People with dextrocardia, a defect, have their hearts on the right side.
Coffee drinkers are less likely to be hospitalized due to heart rhythm disturbances even though the caffeine in coffee can make the heart beat faster. A surprising new study found that those who reported drinking four or more cups of coffee each day had an 18% lower risk of hospitalization for heart rhythm incidents. Those who reported drinking one to three cups each day had a 7% reduction in risk.
Hearts can literally be broken. Losing a loved one can bring such overwhelming feelings of grief, depression, and anger. For some people, the shock and stress of bereavement may even bring on a heart attack. A recent study of nearly 2,000 heart-attack survivors found that attacks were far more likely to happen soon after the death of a family member or close friend than at other times. The risk of having a heart attack appears to decline as grief subsides.
