Looking Young May Cause Longer Living

A 2001 Danish study found that people who look younger than their age live a longer life on average. The test conducted physical and cognitive tests on more than 1,800 pairs of twins over the age of 70 and tracked how long the twins survived over 7 years. The test found that the people who looked younger than their age were more likely to survive, even after factors like gender and environment were adjusted.

There may be a possible biological reason. People who looked younger had longer telomeres, a DNA component that is linked to aging. People with shorter telomeres are assumed to age faster. In the study, the people with longer telomeres looked younger than their age.

HPV Test Better Than Pap Test in Detecting Cancer

It is found that the human papillomavirus (HPV) test can be up to 40 percent more accurate than a Pap Smear test in detecting the risk for HPV. HPV is the leading cause of cancer. A Pap Smear can find existing precancerous cells in the cervix, but the HPV test can detect the infection that could possibly progress to precancer in the future.

Most HPV infections don’t turn into cervical caner, especially the ones contracted before 30 years old because the immune system is more likely to fight the disease by itself. For women over 30 years old, it is recommended to ask a doctor about getting both a Pap Smear and an HPV test. Cervical cancer is usually curable if it is caught early.

Test That Predicts Diabetes Years Before It Happens

A test for three proteins can predict if a woman will develop diabetes years before standard screenings find a problem. The three proteins are signs of inflammation that are linked to insulin resistance. Finding out whether a person will get diabetes early could warn the person and influence them to make lifestyle changes before it’s too late.

Stress Weakens Teeth

In Brazil, 14 tests were done that showed that stressed-out people have a higher risk of periodontal disease. Also, increased levels of the stress hormone, called cortisol, might have a negative effect on the immune system and allow bacteria to invade the gums. You can lower stress levels by exercising and sleeping more.
