tears, goosebumps, hair standing on the back of your neck, those kinds of phenomena are probably the body's way of telling our mind what the truth is, reliable information which is the byproduct of a biochemical process. of course you can manufacture tears, but most people have to access some memory of an authentic feeling for that to happen, unless you're a sociopath, in which case all bets are off. the other day, i was recounting to a work acquaintance the fact that i was fortunate enough to have been in attendance at "The Miracle on Manchester". telling that story gave me goosebumps. or maybe it's something else. i would ask Jennifer Lopez, but i don't know her.
