@d-pend, thank-you for your much appreciated comments and support. Yes, concussions and head injuries are really bad and it does take time to heal if at all. Fortunately they are making great gains in neurology research via neuroplasticity. It is very exciting because music therapy, meditation, brainwave entrainment techniques are being used to facilitate the neuro circuits in the brain. With a lot of hard work on the individual, they can form connections to new parts of the brain. Can you imagine how wonderful if people could start using more of their unused brains. That is why I am doing a lot of writing. They say this is good as you grow older! And I am older but young at heart!!! Have a great day d-pend!!!
