So the way to beat this EyeTRAX thing for drug testing is to be
stoned (ill/tired) all the time so your retinal pattern stays
the same.  Seriously, though, it seems like this effect
(changing retinal pattern with physical condition) might be a
problem--you would still be the same person, but would it
necessarily always recognize you as such?
