Your body is truly an amazing organism! It's like no other on the face of our planet. If you wish to have a healthy lifespan you must take care of your body. This ranges from exercise to nutrition. Remember that your body is the physical source of your well-being. It's your temple that hosts your spirit and soul. Point blank, if you don't take care of your body you cannot optimize the fullness of your life.
"Do you not know that your bodies are the temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own." 1 Corinthians 6:19
