I did not the above facts & now knowing the above does not enlighten me much more . The size of the numbers seems to suggest that we might have great capacity .

Interesting facts. I’d like to get the book for a read. It will be fabulous to be able to tell the brain what to think and when to think it as opposed to the other way around.
