The history of gymnastics began in ancient Greece. Gymnastics was a fitness training program encompassing many forms of athletic activity, including running, wrestling and physical fitness routines. Some forms of gymnastics were included in the Olympics.

The Romans continued the practice. The routines became more oriented toward preparation for training as a soldier. In 393 AD the Emperor Theodosius banned the Olympic Games, which by then had become corrupt, and gymnastics, along with other sports, dwindled.

• It is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring.
• Structurally, the nervous system has two components: the central nervous system (the brain, spinal cord, and nerves) and the peripheral nervous system (sensory neurons, ganglia and nerves that connect to one another and to the central nervous system).
• Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component (nerves that connect to one another and to the central nervous system and the autonomic nervous system (regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort).

Salvio D'Armate possibly invented eyeglasses around 1285. He shared the invention with Allesandro Della Spina, an Italian monk who made eyeglasses public.

Déjà vu, French for ‘already seen’, is a feeling of having experienced something already. A feeling of being familiar with the current scenario as if it has happened to us in the same way before. According to a study, about 60 percent of the population has experienced déjà vu.

What makes déjà vu unique is that there is a conflict between the sensation and the actual awareness, a disorienting feeling that one has been tricked.

• Get enough sleep.

• Take some time to reflect on what you are grateful for.

• Also known as Acute Stress Response, the fight-or-flight response is a physiological reaction when we are mentally or physically terrified.
• A stressful or terrifying situation triggers hormones that prepare our body to stay or either deal with the problem or run away towards safety.

• Obsessive worrying. You may find it difficult to focus on other things. You may experience feelings of panic once you have reached the doctor's office.
• Other illness-related phobias. You may worry that you need to see a doctor for minor ailments, fearing they will require medical treatment.
• Postponing doctor appointments. You may put off checkups or even suffer through relatively serious illnesses on your own.

We all have thoughts going on in our heads all the time, stories, reimagining of the past, beliefs and ideas. Many of these thoughts are not in our direct control and can show up in our consciousness in an intrusive manner, without any effort or intention from our side.

These unwanted intrusive thoughts, which are without our consent, can be beneficial, mundane, disposable, or even disturbing and scary.

Our sense of smell works in wondrous ways since the chemical composition of our surrounding change instantly and constantly. Our noses pick up volatile airborne compounds that interact with our olfactory receptors.

The information that we get from our surroundings pass through our noses and then to the core cortex in the brain. We, humans have about 400 types of olfactory receptors which is used to identify many different types of chemicals that have varying odor quality.

ASMR is an emotional state that some people experience when they hear, see, and feel certain "triggers," such as whispering, delicate hand movements, and light touch.

The feeling is described as a tingling sensation that starts from the top of the head and spreads down the neck and limbs. Feelings of euphoria and relaxation accompany this "trance-like" state.
