      Let us enjoy the dosha first. Then we shall search its maker.

      Are not the scientists laggards? I averaged the life span of 118
      dead nobel laureates in physiology and medicine. It is 79.27 years.

      who set them in motion ? That none could know ! Similarly probes
      could take place on consciousness. But one should probe the creator
      of consciousness.

        Dear J,Since when I read this condition of yours somehow you
        occupied my mind. In your latest post when you asked for simulated
        dreams/translogical exercises, I thought that these are no good for
        you as I initiate these exercises just for freshers into the field.
        Then what do I give to you?

        Please go to "google alert".Fill in "human neuroplasticity". You
        will get every information on human neuroplasticity in your E-mail
        ID. Some are trash. Some are just commercial. But you will get great
        ideas befitting to you too. I will be happy to hear about the great
        ideas you get.
        Good luck.
