"My Proteins"

The mysteries of science are sometimes explored in poems and, in this vein, I was delighted to find "My Proteins" by Jane Hirshfield (a poet whose work I like and admire) on page 56 of the September 16, 2013 issue of The New Yorker.   As she explores the riddles of who she is and where she came from, she has these lines-with-numbers (stanzas 3 and 4):

from My Proteins      by Jane Hirshfield

     Ninety percent of my cells, they have discovered,
     are not my own person,
     they are other beings inside me.

     As ninety-six percent of my life is not my life.
          . . .

Look for the entire poem; and enjoy! 
Another exploration of what the self is and isn't may be found in Hirshfield's "My Skeleton"  -- today's Poem-A-Day selection from Poets.org.  Jane Hirshfield's poem "Mathematics" is available here in my post for 23 June 2010.
