19. Blood Type
Being aware of your blood type is extremely important, especially when being treated for diseases and blood transfusions. But it is also handy to know your blood type in order to learn about diseases you might or might not be prone to. According to research, people with blood type O, positive or negative, are not likely to develop pancreatic cancer, whereas those with A, B, and AB blood types have a 44 percent risk of pancreatic cancer.
18. Breast Size
Women who have larger breasts at the age of 20 are at a higher risk of developing type 2 diabetes than women who have smaller breasts. This in part due to the hormonally delicate fat in the breasts that make women more susceptible to developing insulin resistance.
17. Abnormal Hair
Growing hair in places where it should typically not grow is a sign of a health issue you should seek treatment for. Abnormal hair growth on women is the result of polycystic ovarian syndrome, a condition caused by a hormonal imbalance. An excessive production of male hormones in the body causes abnormal hair growth all over the body, especially on the face.
