The Apple Watch won’t hit the market until early 2015, but I’ve already decided I don’t want one. It looks like an elegant, useful and fashionable device. I could see why some others might be counting the days until it hits the Apple Stores, but it’s not for me.

Every year, the Holy month of Ramadan provides us with the opportunity to eliminate unhealthy eating patterns and gives our overburdened digestive systems a much needed break. During this sacred month, the rituals of fasting, night prayer and reading the Holy Qur’an on a daily basis can have a transformational effect on our overall sense of well-being and contentment.
However, now that the blessed month of Ramadan has passed and the Eid ul-Fitr festivities are over, here are 10 tips for maintaining the incredible health benefits and habits that you worked so hard to gain in Ramadan.
The sense of smell (or olfaction) is our most primitive sense and is located in the same part of our brain that effects emotions, memory, and creativity. Our sense of smell allows us to identify food, mates, and danger, as well as sensual pleasures like perfume and flowers/nature. Sudden scents, like smelling salts, will jolt the mind.
The senses of smell and taste, two of the five senses identified by Aristotle, are called “chemical senses” and are sometimes regarded as one sense rather than separate senses. About 80% of what we taste is actually due to our sense of smell. Without the sense of smell, we would only be able to recognize five tastes: sweet, salty, sour, bitter, and savory. A food’s flavor can be altered by simply changing its smell, while keeping its taste the same. In fact, our sense of smell becomes stronger when we are hungry.
Aromas, scents and fragrances, good and bad smells, are all odors or odorants. An odor is a chemical dissolved in air, generally at a very low concentration, which we perceive by the sense of smell or olfaction. Odors are also called “smells,” which can refer to both pleasant and unpleasant odors. In contrast, “stench” and “stink” are used specifically to describe an unpleasant odor. The terms fragrance,” “scent,” or “aroma” are used primarily by the air treatment companies like Prolitec as well as food and cosmetic companies to describe a pleasant odor. The term “perfume” is used to refer to fine fragrances or wearable scents.
Humans are able to distinguish over 10,000 different odor molecules. When inhaled, these odor molecules travel into the nose and interact with odor eceptors. The odor receptors then transmit the information to the olfactory bulb, which is located in the brain’s limbic system. The limbic system also controls memory and emotions, and is connected to the pituitary gland and hypothalamus area that controls the release of hormones that affect our appetite, nervous system, body temperature, stress levels, and concentration.
