when we smile, whether we force ourselves to or not, the act of smiling sends messages via the nerves to the brain to release neuro-transmitter chemicals into the bloodstream. this drug that we just created makes us feel good.
try it now.
no really........look in the mirror and smile.
feel silly and do it again.
now. that`s a real feeling derived from deliberately choosing to feel good.......for no reason. other than the fact that it will save your life.
and the question you have to ask is, if you aren`t choosing your own feelings, who is?
