heart failure

my heart has no owner. this heart in my chest isn't mine. it isn't yours. it belongs to no one, miss someone. because it beats without a reason. all the other muscles get tired. this one i don't even feel moving, crushing into itself and exploding more than a thousand times per minute. or less. much less now, i guess. and while it happens the dna sequence gets tired of its work and begins to make some mistakes. one of those mistakes could get me a wing, or a new tail. but most of those changes ends in great failures. no planing. as i said, this heart has no owner. no desirable end
