We may like to assume that we are adults when we turn eighteen; however, the truth is our brain is still undergoing a significant amount of construction until our mid-twenties. Research has shown that the brain is not fully developed until a person reaches about the age of twenty-five. For males, full development can extend until the age of twenty-eight. What does this mean for you? If you are under twenty-five, this means every decision you make, every thought you have, every action you take, all the food you eat, the amount of sleep you get and everything else you do throughout your day has significant impact on your developing brain.
