The Brain Rejects Inequality
The human brain likes balance. Not simply biological and physiological homeostasis that maintains the proper functioning of the brain, but emotional, social and psychological balance. Notably, the human brain dislikes inequality when it comes to money, and rejects it at all costs, according to new research in the journal Nature.Behavioral and anthropological evidence show that humans dislike social inequality and unfair distribution of outcomes. But this evidence is not purely social, anymore, since researchers at the California Institute of Technology and Trinity College in Dublin, Ireland, have identified reward centers in the brain that are sensitive to inequality.
Good Health Equals Good Sex
Sexuality is an important component of overall health and quality of life. An active sex life can reduce stress, strengthen the immune system, improve cardiovascular health and promote longevity. Not only does sex lead to health benefits, but good health leads to improved sexuality. A recent British Medical Journal (BMJ) report concluded that the better one’s health, the more sex he or she can look forward to later in life.
The Neurobiology of Social Anxiety Disorder
Shyness is a unique trait and all of us experience it in various degrees when faced with performance situations or new social surroundings. However, many people go through life dreading such encounters and exposure to the feared social situation provokes anxiety, or possibly a panic attack. Social anxiety disorder (SAD) or social phobia is a common anxiety disorder in which individuals shun all forms of interpersonal contact or undergo extreme physical or mental discomfort in social settings. Until recently, this condition was dismissed as ascribing pathology to a normal variant of human personality in order to sell treatments. However, most psychiatrists now believe that social phobia is not a pathological label for shyness. Shyness neither is a prerequisite for nor can be considered as synonymous with social anxiety disorder.
Leg Length and Osteoarthritis
At least 20 million people in the United States have osteoarthritis. This prevalent type of arthritis is most simply age-related wear-and-tear of joints. As people age, cartilage that protects the body’s joints breaks down, leading to joint pain and stiffness. Osteoarthritis normally appears after middle age and can cause significant disability if not treated. However, most osteoarthritis is manageable with over-the-counter pain relief, physical therapy and exercise. Physical activity is also the most effective prevention for osteoarthritis; maintaining a healthy body weight and avoiding injury can reduce the risk of developing osteoarthritis. Now, a new study reported in the Annals of Internal Medicine claims that leg length discrepancy is a modifiable risk factor that mitigates the risk of osteoarthritis.
