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.
But, if you are eating a balanced diet, most doctors expect you. to void at least once per day, more if you're eating a lot of. vegetables and other foods with roughage. Bowel movements vary in color and smell. If you are eating a. vegetarian diet, your stool and flatulence will smell somewhat. more pungent at first.
