It works for me. I have a particularly sensitive sense of smell. I have walked across campus and entered a perfume wake ten feet from a female and have been able to detect the scent that she is wearing.
I have a sensitive sense of smell, too. Some things just don't register, though.
And aftershave or cologne has the same affect on me...makes me want to follow...Tabac is good...so is Polo...but Elsha is my favorite...and may not even be made any more...
