I spend so much time and energy juggling the uncooperativeness of my body that I often neglect to take stock of what's going well with it.
So! Things that are going well as of right now:
Alive and listing toward quality
Never had a cavity
Heart is anatomically normal
Blood pressure is always satisfactory
Hearing is typical
Kidneys and liver function as expected
Skull protects my brain like a pro
Brain fights for me even when it doesn't
Most of my body responds well to low-impact exercise when I can get it
No doubt there are more, but that's enough for me to gather some perspective by today.
