Have heard of neurologist propose system termed "Neurobics"
claims to have validating data, I haven't seen it.

Here again the problems were due to novel protiens produced by
*genetically* *engineered* tryptophan sources. Although the
people who suffered, some died, were taking innapropriately high
doses. However, it is worth noting that the problems would not
have occured with naturar non GE sources.
Now I know you're all thinking I'm spreading anti GE agitprop,
nevertheless the _facts_ have been already established, and
GE was implicated.

Very true, Glutamate is a mildly pleasant and comfortable neurotransmitter
to stimulate, from a perceptive point of view, but rots neurones far
faster than sugar does teeth. So easy with the soy sauce.
