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.
Why does my urine smell like the food I eat sometimes? This morning it smelled like bacon. Some foods contain substances such as sulfur or ammonia-like compounds, that produce a noticeable odor when theyâre eliminated in urine. Other body fluids may be affected as well, such as sweat or semen. A common culprit is asparagus, which will give urine a distinctive smell only 30 minutes after you eat it. Other foods or substances (i.e. alcohol or cigarette smoke) generally change the odor of urine or other body fluids to a less noticeable degree, unless the food or substance is consumed in unusual quantities.
