Of course, the telltale sign of Alzheimer's disease is memory loss, but dementia also manifests itself in your eyes. In a 2019 study published in the journal Neurobiology of Aging, researchers noted that the disease affects the locus coeruleus, a cluster of neurons in the brainstem responsible for pupillary responses, among other things. As a result, individuals with cognitive impairment who are at risk of developing Alzheimer's have greater pupil dilation while performing cognitive tasks.

Though definitely unsanitary, peeing in a pool might seem harmless for your health. After all, urine is sterile, as is chlorine. As it turns out though, urine and chlorine create dangerous chemicals when combined. In fact, that so-called "pool smell" is actually the scent of those chemicals, as Xing-Fang Li, an environmental chemistry professor who conducted research on the topic, told NPR. One of those chemicals—cyanogen chloride—is classified as a chemical warfare agent and can damage your heart and lungs. Other byproducts, called nitrosamines, can even cause cancer.
