Your brain produces enough electricity that can light a light bulb

Your brain produces enough electricity that can light a light bulb. Your brain has around 100 billion microscopic cells, known as neurons. Whenever you think, dream, laugh or walk, tiny chemical and electrical signals are racing between these neurons, along billions of tiny neuron highways. Believe it or not, brain never stops its activity. Incalculable messages dash around inside it consistently like a supercharged pinball machine. Your neurons make and send a larger number of messages than all the telephones in the whole world. And keeping in mind that a solitary neuron creates just a small measure of power, every one of your neurons together can produce enough power to light a low-wattage bulb.

The research shows that listening to music, initially produces varying levels of arousal which may result in accelerated breathing, increased blood pressure and heart rate. These symptoms are directly proportional to the tempo of the music and perhaps the complexity of the rhythm.

#7 You are 1 cm taller in the morning than you are at night.

You are 1 cm taller in the morning than you are at night. While we are at sleep or lying down in a resting position during night, the spine is said to “spread out” or decompress. So, when we get up in the morning, we are taller after the rest in bed all night.

Our Stomach acid, also called gastric acid or gastric juice, is comprised of Hydrochloric acid (HCl), potassium chloride (KCl), and sodium chloride (NaCl).  The PH value of this stomach acid is generally between 1-3, which is very acidic. Also, to mention that, these pH levels put stomach acid in almost the same category as battery acid, which can dissolve steel.
