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.
So brush up on this toilet trivia, and then pay attention to how often you go, how long it takes, and what the end result looks and, yes, smells like. Simply put, know your poop. Water makes up about 75 percent of your bowel movements. The rest is an often-stinky combination of fiber, dead and live bacteria, other cells, and mucus. Soluble fibers found in foods like beans and nuts are broken down during digestion and form a gel-like substance that becomes part of your poop.
