This poem really gets to me.
In a good way, I think.

"so now your body
starts to get old
only to rot
and turn into mold"

I like how there you didn;t go too far overboard with the gore. (some people try to to make it "good." but often it just makes it sound fake and forced.) But the fact that you used the word "rot" instead of, say, "decay" or something. It would have the same effect, but the word "decay" would add weight, so to speak, to your lightly imaged poem.

Wow. That was long. But eek, like I said, this poem gets to me. I like it a lot. :)
