We acknowledge that Tigger is gregarious and affectionate, but he has a recurrent pattern of risk-taking behaviours. Look, for example, at his impulsive sampling of unknown substances when he first comes to the Hundred Acre Wood. With the mildest of provocation he tries honey, haycorns and even thistles. Tigger has no knowledge of the potential outcome of his experimentation. Later we find him climbing tall trees and acting in a way that can only be described as socially intrusive. He leads Roo into danger. Our clinical group has had its own debate about what the best medication might be for Tigger. Some of us have argued that his behaviours, occurring in a context of obvious hyperactivity and impulsivity, would suggest the need for a stimulant medication. Others have wondered whether clonidine might be helpful, or perhaps a combination of the two. Unfortunately we could not answer the question as scientifically as we would have liked because we could find only human studies in the literature.
The whole thing is here. Quite entertaining.
Edited to add: Found via Podblack. Lots more good stuff there, too. I'd have credited it earlier, but tabbed browsing is a great way of losing sources.
