It's the same for us all

This is a beautiful evocation of the transience of life, one of the most original I've read for a while. The structure is solid, there's no emotional manipulation, the rhythm lends itself to the gentle contemplation of the lines. One for my list.
I think you meant "secret" instead of "secrete" in the sixth line by they way.

Thanks!
And actually, when I said secrete I meant how a heartbeat can be pounding away and other times barely there, seemingly hidden.

Oh I see! Thank you so much for clearing that up. Gives me yet another perspective on the piece.

RE: "secrete"
Then it would be "discreet", no? (and you don't break the rhyme).  I don't understand the context of "secretion" as an antonym for obvious (or just plain contrast).

I think this is one instance where rhyme is forgiven and almost a requirement.  The rhythm of the poem is pretty good for the most part.  I wasn't quite sure about "If in a sort of agony", it feels a hair too long, maybe just drop the "in".

Overall, some good ideas, well expressed.  Pretty good stuff.

I looked up discreet and don't quite understand the meaning? (I'm not being defensive just explaining my thinking)I was thinking that since obvious is to be right in front of your face, and secrete means to conceal it would be a contrast. Or would I have to have secreted?
Thanks for the suggestion, you're right, it would flow more without then "in".
Thanks for your help, I'll work on figuring out discreet.

I don't want to get all technical and pretend to be some grammar/word expert because I'm not.  I think I understand what you're trying to do with "secrete" as in "He secreted her away to some unknown destination", but when I see the word here in the context of your poem I think of the verb "to secrete" or to ouze out a substance (not what you mean at all) because this is the more common use of the verb.  I guess you're not wrong, it's just hard to get the context here in the poem ,and then if people misread your poem, they misunderstand it.

Discreet means to not call attention to, to do in a manner that is more private, less public.

Okay, I get what you mean. Oozing out isn't really what I'm going for, and I totally understand you getting that.
Thanks for the definition, I like that...I think I'll use it. Thank you!

I personally think that works better, and the rhyme isn't broken either. :)
