Sweat, and a clinging sheet.
My flesh was its own shield:
Where it was gashed, it healed.
I grew as I explored
The body I could trust
Even while I adored
The risk that made robust,
A world of wonders in
Each challenge to the skin.
I cannot but be sorry
The given shield was cracked,
My mind reduced to hurry,
My flesh reduced and wrecked.
I have to change the bed,
But catch myself instead
Stopped upright where I am
All that he was, is gone. His formal self is lost, gone with tides and everything from past taken away.
