I think it all boils down to .... Does the animal that's smelling the scent molecules we introduce to the area....do theyassociate these odors with danger...?????? no matter if you're covered in cowchit or apple scented shampoo... Each and every deer/any big game animal for that matter...is different and associates different stimuli with danger...based on thier experiences with dangerous situations ie...predators or hunters..

I also believe we allleave some human odor; obviously some much more than others especially in relation to how we prepair ourselves before a hunt..I believe minimizingobtrusive scent moleculeshelps lesson the chance of a critter blowing out of an area versus possibly checking things out and then continuing on their normal/natural route of travel..
