The science of gerontology has evolved as longevity has improved. Researchers in this field are diverse and are trained in areas such as physiology, social science, psychology, public health, and policy. A more complete definition of gerontology includes all of the following:
Smelly bowel movements are caused by the release of gas. when bacteria, bile or acid mixes with food. Depending on the. food you eat, and where in your digestive tract the mixing. occurs, the combinations can produce various types of gas, all. with different smells.
Smell is the most subtle of senses touched by spring. In spring there is the sweet fragrance of flowers, which is perhaps the first thing many think of. But my thoughts are drawn to subtler scents. In winter the sun is low and weak, giving little light and even less warmth.
