It is in your hands
Everything discussed here will remain a weapon in your hands, but you would have to use it for your defence. Knowledge on its own lacks power; it is action that wields change. Staying healthy is a possibility and that depends on your everyday choice. Every decision you make determines if you will be healthy or unhealthy.
Decide that you will eliminate unhealthy habits and embrace positive ones. Decide to change your diet and exercise. Eliminate excuses and you will live healthier than you have ever done.
