Hope Passover was warm and friendly with all the =amily around.

Have run another set =f "open label" experiments. Certainly there are some =hanges with the light but a wide variance which we will need to =imit.

Probably 1 more open set then =first blind random trials.

My =kype has lost its data so will let you know when I can skype =gain.
