lifespan (EDIT 1) lifesize

[Todd]

Hi Kole, let me give you a few comments. I like the conceit of this, the shape of it, and overall what you're trying to do.

even before birth--Good opening line. Evocative and Interesting
we begin to grow--I don't like lines that just make flat statements. You can cut them usually and lose nothing at all. If you simply moved to line three what is lost?
cells inflate a moving body
empty belly to inflated lungs crying--empty/inflated is a good contrast.
so many meals leads to playground speak
opinions tested as longer lung inflated air heats--I see what you did with air heats. I you are using inflated quite a bit throughout. This is the third reference in a short space. Maybe express the idea without using the tag.
18 pretending so many words are adult body growing--You use two numbers as numbers 18 and 30. I'm not sure what they really add. 18 is a quick adult tag so I get that purpose. I think they draw attention though that I'm reading a poem. Might work better as eighteen (hard to say could be style).
monkey hanging from buildings over yellow night roads taunting death--Like this line a lot. The image is interesting. I think though that you may want to change taunting death into something else. Thematically I don't know if I'd mention death in the poem. Just a thought. taunting gravity maybe.
conceived children from tooth sweat red markings at bruise green 30--This is also a really nice line. These last two lines might be a good model to readdress the entire poem with the more interesting language choices. I'm not saying the other lines are deficient but these two are definitely a departure from what's around them.
from here the body starts to shrink back into itself--a little too flat observation.
chase the children raw brain tired past sun logic--again love the language here.
into a mirror these children growing taller older
my wife and I an empty house--last two lines a bit on the flat observation side.
alone again a little grayer smaller--Not sure I like "a little"
sex still good but older--flat reportage
worry evaporating night dew--lovely (like the dual use of evaporating to the left and the right)
we hold hands
going blind
until--solid good ending

A little much for mild maybe, but I liked the poem and wanted to give the comments. I hope some of them help.

Best,

Todd
