First, I would like to give a thumbs up on the topic. The topic is simple, concise, and explains it all. It encapsulates the whole story. You must be a good writer. Kudos! Reading your post almost made me start feeling pain in my chest, especially when you wrote about laughing too much. There is this saying of mine which I believe so...strongly: "Worries are one of the abstract exercise that weighs more than a thousand tons of lead". We do not see them, but engaging in them gives more than the feeling of being loaded with 500 liters of water on the head.
