This still doesn't explain how it works. Oxygen and heart rate can be done with light, this is well known, but how does it measure glucose and alcohol levels and blood pressure?

If someone is really drunk you can smell the alcohol standing near them. Not sure about glucose but possibly it's detecting chemicals diffusing through the skin or pores?
