Up to 60% of the adult human body is made up of water. Research has indicated that both the human brain and heart are around 73-78% water. Your brain isn’t fully formed until age 25. Brain development begins from the back of the brain and works its way to the front. An adult brain weighs about 3 pounds. Information runs between neurons in your brain for everything we see, think, or do. These neurons move information at different speeds. The fastest speed for information to pass between neurons is about 250 mph. The brain can’t feel pain. It interprets pain signals sent to it, but it does not feel pain. The human brain gets smaller as we get older
Alcohol effects your brain in ways that include blurred vision, slurred speaking, an unsteady walk, and more. These usually disappear once you become sober again. However, if you drink often for long periods of time, there is evidence that alcohol can affect your brain permanently and not reverse once you become sober again. Long term effects include memory issues and some reduced cognitive function. Your brain uses 20 percent of the oxygen and blood in your body.
When the blood supply to the brain stops, it is almost after 8-10 seconds that the brain starts losing the consciousness. The brain is capable of surviving for 5 to 6 minutes only if it doesn’t get oxygen after which it dies. The blood vessels that are present in the brain are almost 100,000 miles in length. In early pregnancy, the neurons develop at an alarming rate of 250,000 per minute.
