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.
When you canât smell things you enjoy like morning coffee or flowers, part of life may seem very dull. As you get older, your sense of smell may fade. Your sense of smell is closely related to your sense of taste. So, when you canât smell, food may taste bland, and you may lose interest in eating.
