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.
A person with a healthy colon will have 2 to 3 bowel movements per day, shortly after each meal taken. Elimination should be complete and easy. The stool should be light brown in color, long and large diameter. There should be no offensive odor and it should break apart with toilet flushing.
