Why health? Health has more impact on your everyday life than you realize, and here's why. Your physical health is tied to your mental health. Did you know 95% of the serotonin in your brain is produced in your gut? And over 50% of the dopamine in your brain is also produced in your gut? Did you know almost any disorder or disease can simply be cured or almost completely be ridded just by eating right? Physical exercise is also one of the best things you can do for your health, but just like a car your body deteriorates without the right fuel no matter how well you treat it.
