Yea, you&#x27;re probably right about moderate levels of sport. On a very direct level, faster blood circulation from exercise improves brain function. There&#x27;s probably also some motivation&#x2F;self-esteem feelings it helps with as well.<p>I wonder if in a generation we&#x27;ll see posters encouraging kids to play video games instead of blobbing out in front of the Facebook or whatever the new bogeyman is. I get the feeling that using a computer (or phone or whatever it is) is becoming accepted as default OK and now it&#x27;s the specific types of app that can be &quot;good&quot; or &quot;bad&quot;.
