Our brains are made up of 60% fat. It is the organ in the body composed of the most fat. It is important to feed your brain and body good healthy fats to stabilizes the cell walls of the brain. It was formerly believed that brain functions decline as we age. New studies such as the one done at Harvard University show that arithmetic skills peak at 50 and that cumulative intelligence (all the facts we have learned in life) peak at 70. A fallacy is that the size of a person’s brain increases intelligence and that a person’s IQ is permanent. However, IQ can go up or down at different stages in our life. The brain has extreme plasticity which means just as a person can adapt to a missing limb so to can the brain adapt to a damaged section. Problem solving, judgement and complex planning do not fully develop in the frontal cortex until age 25 which is why teenagers can sometimes make irrational decisions. The brain itself feels no pain. It is the nerves and blood vessels surrounding it that have to be deadened during surgery. The brain is wired to make neural connections with others which is why good friends often enjoy the same activities and musicians can form such a tight union. The neurons in your brain produce enough energy to light a 20 watt bulb daily. It is faster then any computer and messages are sent from the arms and legs at 150 MPH. How do we keep the brain healthy? Is there a way to strengthen the capacity of this organ? Research is showing that healthy gut bacteria, sex, vacations, laughter, exercise, healthy eating and meditation are important factors.
