Ferrous.

Ferrous
Ferrous is what I feel when

When flesh is made
Caustic and rough
By the windchill and the carbon
Toxic smoke
Ferrous is what I feel

When I look down
Cycling through
A life left on the pavement and
A moisture-lost leaf reaches
Up and through my pupils
Takes my brain
In its metallic undying and deathly hand
Ferrous is what I see

When flesh is made
Permeable
Prickly, spiky
By the windchill and the tobacco
Ferrous is what I feel
Ferrous is what I taste
The ions on us tingle
Depriving you of water
And we're sour in each others' arms
Like running your tongue along a lamp-post
Or your keys

Ferrous
And toxic and tingly
Exchanging ions all the while
