Homo sapiens evolved in Africa as a hairless ape. That creature spent LOTS of time outside, with a prodigious amount of skin exposure in a nice sunny environment. Today homo sapiens is largely an indoor mammal, and typically covers up a good deal of skin when venturing outside. Even when in a relaxed stance, say...

Even though muscle is heavier than fat, and exercise greatly stimulates appetite, no health improvement or weight loss program will ultimately succeed without focused toning. This is because muscle is hugely metabolically active tissue and uses up close to 80% of our glucose requirements. In general, I favor low carb (and no refined carb) diets,

If you suffer from seasonal allergies, you are not alone. Twenty percent of the US population (about 50 million people) make over 10 million visits to doctors every year for this common concern. Multiple factors conspire to create the dreaded days of runny noses, itchy and watery eyes, relentless sneezing, scratchy throats and just generally...

Nature is very efficient.  Good designs, no waste.  The purpose of the gallbladder is to store a small repository of bile, which serves many important functions.  Bile requires a good deal of energy and biological resources to produce in the body.  It is vigorously recycled.  It is what makes the color of a healthy stool...
