Next time you feel like telling your spouse that you love him/her, just tell him instead that you have an itch or a gastrointestinal pain. It means the same thing in your world....ie...a neurohormonally mediated chemical response inside brainmeat,significant of nothing. Chemicals simply react and that reaction logically has no meaning what-so-ever.
