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.
Normal Stools. An ideal bowel movement appears medium brown and has a slight smell. It should be easy to pass, with little strain or discomfort. Occasionally, your stool might have a different hue. If this is the case, consider what you've eaten. Beets or red juice can color your stool red.
