Sure I'm probably biased but I believe sleep quality is a little more difficult to control than the other points you listed. I can't even fathom consciously having bad sleep habits and not fixing them given how disrupting insomnia has been for me.

Honestly, my wife has insomnia and it is not only difficult to manage but it interacts with all the other issues: increases stress, makes eating healthy difficult (reduction of will power) and exercise is harder to recover from.
