This isn't going to be a long post, but I just wanted to make a few quick points that you might not know about that is something interesting and possibly useful to know:
1. Being in sunlight increases serotonin in the brain. That is why we feel happier when the sun is out compared to when it's dark and rainy.
2. The brain size of someone who is overweight has four percent less volume than those not overweight (from BMI numbers) and looks eight years older. For those who are obese, the brain has eight times less volume and looks sixteen years older. Wow.
3. Someone with an extremely low BMI (such as someone with anorexia) also has a smaller brain than someone with a regular BMI.
BMI = body mass index

4. The brain is 60 percent fat! Much of our gray matter, which are the dendrites and cell bodies in the brain, contain large portions of the omega-3 fatty acid DHA (or the more confusing docosahexaenoic acid. Neurons are rich in omega-3 fatty acids, which is why it is important to eat foods with healthy fats, or take a supplement.
