Brain Health and nootropics

Brain health is on everyone's mind, yet little is done about it.
Here's a quick guide to staying sharp.

-Eating a healthy breakfast with grains, fruits, and a protein portion like eggs or fish.

-Uninterrupted sleep at a daily regular bedtime will do more for your mood and brain health than anything else.

-Math, puzzles, word puzzles, working in teams to solve problems and going back to school as an adult will rejuvenate your brain to a younger age.

-Mindfulness, meditation and taking a short break from work will allow the brain to eset and function much to our liking.

-30-60 minutes of daily exercise to help keep our blood circulation going can keep our body's aging process at bay.

-Certain food supplements may also help this process.
