The vitality secret

 Health becomes automatic
strength lives inside the body
My legs carry me 
agility through every vein

I recieve vitality here
on the modest field of grass
On thick asphalt
In the small spaces the town is made of

moving forward
And upward
up up up
attitudinally up

lungs devour air
legs meters
mouth food
ears words

I tend not stop growing
I become more and more vital despite my age
And there is a secret to it
But I cannot share it with you
