Stress will fucking kill you. Now, we don't have any control over the things the world throws our way that can cause us stress but we do have a say in how we  are able to handle it. Mostly for guys stress escapes us in the form of aggression so doing good things to release that aggression that contribute to our long term growth allows us to take back control over ourselves so we don't have to be so reactive to whatever situations we find ourselves in.
