I no longer have to be face down, and the bubble in my eye is now shrunk out of sight. Who knew that simply being able to lie on one's side in bed is such a luxury? It is similar to being away from the comforts of home and realising that hot running water - just taking a shower - would be an almost unimaginable luxury for most people in human history. We are not grateful enough.
I will, of course, revert to being spoiled and ungrateful rapidly, as humans are likely to do.
