When I don’t have a headache
When my eyes don’t ache
When I don’t stumble on something invisible
When I don’t drop something
When a knee doesn’t buckle
When I don't fall
When my legs don’t become leaden walking up the hill
When the ringing in my ears is quieter
When my legs don’t ache
When a muscle spasm doesn't wake me
When my feet aren’t stiff in the morning
When I don’t choke drinking a glass of water
When I don’t wet my pants in public
When my bowels work as the creator intended
When I can be outdoors on a summer day
When my fingers don’t drag on the keyboard as I type.
