Health problems detected with sniffing device

We now have news out on another small device for diagnosis health issues: this one uses sniffing to detect health problems varying from Alzheimers to a deviated septum.

The idea is that the sense of smell is one of the most delicate of senses and may act as a sort of "canary in the mine" to give early warnings of impending or already existing issues. By measuring how deeply a person sniffs when smelling a scent or odor experts can determine if their sense of smell is impaired or not, and then find out why if it is.

I hope I'm not asked to take this test anytime soon because the smells they use include ripe cheese mixed with rancid meat, burning mixed with skunk scent, and then (a sigh of relief for participants) bananas.
