Liz, (and any inventors out in list-land), I was thinking, what could be devised, or adapted to amplify the "smelling" process? We have hearing aids to amplify sounds for the hearing impaired, eyeglasses for those with weak sight, why couldn't a device to concentrate odors, or maybe direct them better, be made for those with a loss of ability to smell? I can't believe the technology does not exist, but I can believe that the problem is not considered serious enough to deal with. Any ideas? Ken B
