T. S. Eliot's "The Love Song of J. Alfred Prufrock" is the monologue of a sexually frustrated middle-aged man with unfulfilled desires and an "overwhelming question" (which is never specifically identified), but the line "Do I dare disturb the universe?" seems to cover all bases. However, we do not know more specifically what Prufrock means.
Lines 37-48 reveal Prufrock in his current state: his thinning hair, skinny arms and legs, his coat drawn tightly up around his chin all suggesting his age and decrepitness. Prufrock is more than aware of his appearance; he laments him age and the current state of his body. Despite his age, Prufrock still imagines a different life, one the challenges himself and his surroundings. Unfortunately, it is never meant to be as he only wait "till human voices wake us, and we drown."
