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.
Bowel Movement Immediately After Eating a Meal. Bowel movements that occur immediately after eating have nothing to do with the meal that was just eaten. The digestive path that your food must travel between your mouth and your butt is long, twisty, and will cause a delay of at least a few hours.
