My son said it is dangerous for young children to be exposed to 3-D. As I understood him, their brains will be re-wired before they are even wired for functioning in this world, the "real" world as we perceive it.
Professor Phillip Zimbardo is fascinating in his look at how we perceive and utilize time. I had seen the first part before but then he continues on, and maybe I had seen the whole thing but I didn't take it in as strongly until the discussion with my son.
What I see in Toastmasters is how important it is to have human contact. I realize that when we clap, we smile. I don't think we can clap without smiling and Toastmasters is about clapping, is about encouragement. We need touch, the touch of our two hands coming together to make a sound, and the touch of others, the accolades of their eyes, their hugs.
We need to stay aware of how we are raising our children. We need to stay in touch.
