Sir Godfrey Gregg
Your body is the vessel in which you experience life. If you want to experience the best possible life that you can, you have to maintain your vehicle: give yourself the proper fuels, get regular checkups, and continue to enjoy your body. One major factor in enjoying life is enjoying it in the best possible way, through a well-rested, healthy, and well-maintained body. This is the only body you are going to get, make sure it does not fall out of use earlier than it should.
