Exercise it. Physical exercise is the best thing you can do for your brain.
Feed it Fat. Our brains are mostly fat and the brain needs fat for fuel. But feed your brain good fats like Omega-3’s, nuts and seeds.
Stimulate it. To do this you must learn something new and hard. The easy stuff doesn’t get your neurons firing.
Play with it. Play is very important for brain health. From video games, board games, cards and surfing the net.
Serenade it. Music can enhance moods and better sleep and lower blood pressure. Of course, make sure you listen to classical, jazz and other soft sounds - and not thrash-metal [at least not right before bed or a meeting in which you need to maintain your cool].Meditate it. Meditation boosts brain functioning as well as the immune system. So get your Ohm on.
