It is not often that we sit and reflect on the internal workings of the body. When was the last time you thought about your heart beating or your food being digested? In fact some people never think about it. I would like to share with you the wondrous internal workings of the body and the daily gift it gives to you so in turn you will have more appreciation for the life it brings to you. I also want to increase your awareness around the many functions taking place and how your attitude, your level of gratitude and your physical (move), chemical (eat) and emotional (think) health can have an impact on your bodies function and it’s ability to keep you healthy in all areas of your life.
As you read through these remarkable facts on the body, stop to integrate them into your daily life. Always remember that your body is a self healing, self-regulating and self regenerating organism which is constantly adapting to its environment…all coordinated through your nerve system.
