Anything less and you are selling yourself (your body) short. Not exercising , eating wrong and neglecting yourself is the equivalent of leaving a beautiful muscle car out on the grass to get punished by rain , sleet and snow.
Sure you can always go out there and sand away the rust and do some body work and add a fresh coat of paint but no matter how hard you work it will never truly be mint again. Same goes for your body. We can relentlessly batter our selves in our youth but when we get older you can work for years to try and reverse the damage done. You can gain back some of your health and vitality but you will always have to settle for the fact that some of it is lost forever.
