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.
Gastricolic reflex: When you eat , you GI tract gets activated in order (mouth to rectum/anus) like a tidal wave. So you may feel like having bowel movement 30-60 min after meal. Your stool is not what you ate , is what was stored in the colon (it takes about 16-24 hrs to digest food before it turns into stool).
