You get attention. Unexpected kindness. A lady came up in an airport lounge and served me some food, seeing me having some difficulty opening the heavy lids. I was grateful. Airport security also gives you more attention, by the way :)

You get a new wardrobe- to fit the accoutrements you are forced to wear, like the cast.
You are a temporary POP star, if not a rock star- the Plaster-of-Paris cast ensures that!
You meet some good doctors-I did.
You learn what insurance pays for and doesn't. Useful info in life.
Life does not change permanently, but it does change perspective.
