Sam J. Charlton said this quote

There are different kinds of anger. There is the kind that flares bright, like a fire devouring dry wood – an anger that dies as quickly as it ignites. There is the kind that takes its time to rise, but leaves devastation in its wake when it does. And then, there is the anger that is always there, in the pit of your belly – gnawing, biting and twisting – and reminding you of its presence every waking moment. This is the kind that can kill you, if given enough time.
