Watching a cut, burn, or bruise heal is the most gratifying experience. To slowly watch the process of your body rebuilding itself around the injury reminds you of how powerful the human body truly is. To see an armor of scab or a leathery padding of a blister is to know that your body is looking out for you. I may not see the cells moving by the second, but I wake up one morning and I am more healed than I once was.
