Exercise has innumerable health benefits, but losing weight may not be among them.

When it comes to the vocabulary of sensory perception, smell is at a significant disadvantage - especially if you speak English
Several years ago, the sensory psychologist Avery Gilbert wrote a blog post on the subject of body odor in the erotic romance novel “Fifty Shades of Grey,” by E. L. James. The book, he observed, is liberally scented. At one point, its male protagonist, Christian Grey, is said to be redolent of “freshly laundered linen and some expensive body wash,” which prompts its female protagonist, Anastasia Steele, to announce, “I want to breathe this elixir for eternity.” Ana’s aroma is equally enticing...
