Even too much Exercise
There are some things that are beneficial in moderation. But if you notice you can’t escape, if you have become addicted, then you have lost your control. No longer are you free but have become a slave to your passions. You have become a slave to your flesh.
We all have a strength within our minds to control our bodies. We can restrain our need for immediate gratification knowing that there is something over the horizon that is much grander. We can be the kings of ourselves, if we put our minds to it.
