I had what sounds like a similar health experience to yours in my mid-twenties, and ever since then, luxury has been the ability to walk. Even almost fifteen years later I really haven't gotten over that. I had come to terms with the idea that I probably wasn't ever going to again, and after that unexpectedly changed I have never gone back to taking it for granted.
I have a lot of other luxuries in my life these days but that's the one that's most viscerally meaningful.
Poor health puts perspective on many things and I think those that experience it early and recover generally end up better off for it and have different views of the world. It is sad when the 'sickest' among us have the healthiest views of life. Perhaps one day we can learn the same lessons whilst healthy.
