There are many kinds of therapy. The type that I feel is most restful for the brain is writing. The time just passes away.
I was just reading about using Twitter and Facebook. Many people also find using social media a therapy as well. Some members of my family tell me that television is out and communication through social media is in. Particularly YouTube. I noticed that many webinars that are available are now shown on YouTube. Some of them were once a paid program. Now the instructions are free. When I was teaching at VCU we often went off onto YouTube to find a stimulating opening introduction to the day. The students enjoyed it and let them catch their breath before diving into the assigned lesson.
