Our PM may have to do a lot of sitting because that is an element of his role. However, we should never be lulled into believing he is being complacent when in a physically sedentary context.

His eyes and his mind are constantly on the go, absorbing and considering everything going on around him.

He is never inert or unaware, but rather is carefully considering and appraising every situation and the entire context of every conversation being directed at him or to others in the group.

A man most active is our Prime Minister.
