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.
The heightened sense of smell that occurs during pregnancy may be connected to the changes in taste that often occurs during the second trimester, as much of our taste comes from the smell of food. Finally, your other senses may change as well during the second trimester.f all of the senses that change during the second trimester, the sense of smell and the sense of taste seem to be the most pronounced, although changes to the other senses during the second trimester are not uncommon at all.
