To think! We muast to seat?

I think that we can thing doing most anything. though it may be more difficult as our attention will be divided.

If I am reading what you say correctly, you are suggesting that a person can think and learn while standing, sitting, dancing, walking and running. If that is the premise, I would have to agree. As all of these aspects involve some kind of physical activity, messages have to be sent to the brain and to the corresponding muscle groups to follow through and complete the activity. There are definite thought processes going on with all of these activities, and a person is learning throughout the process, whether it be standing, sitting, dancing, walking or running.
