What an interesting concept. It is great for the brain. I recently did a study on neuroplasticity and found that new discoveries have taken place in this area. The brain is constantly developing new neuro pathways which is amazing because traditional medicine has always felt that the brain didn't regenerate. Now we know it does.

I love the idea of mental writing and in fact I have been doing a lot of mental conceptualization before writing. It is remarkable how writing has really given me a boost in mental alertness and happiness.

You are doing great d-pend. You seem to be evolving everyday! It is something to see and be proud of! Take care and keep doing mental writing! :D
