How does that breath test work in practice? I specifically wonder about the hygiene of the mouthpiece if there is one. Is there a disposable mouthpiece included when you use the Health Monitor?
There would have to be. No one would use something that someone else just had their mouth on. Plus you just need someone to contract a disease from it, and you have a lawsuit.
As I know, this diseases (cancer and diabetes) are not contagious. And other diseases can be infected in other places - for example, in restaurants or metro. Though I think methods of protection should be provided.
