@David Eddleman, re: learning experience.
If you read my post all the way through, you would find I did not exclude any appropriate treatment for traumatised patients. I merely suggested that beta blockers should not be used as a panacea, as some drugs have been with unfortunate consequences,
As for the learning experience, it is, at all levels, the basis of our lives. Starting with our parents (or carers), siblings, then childhood friends, teachers, more friends, colleagues, strangers (friendly or otherwise), work, vehicles and other machinery, the media, world politics, whatever has shaped our view of the world.
For myself, I hate the idea of losing any of that, but I can also see that it may sometimes be necessary to help some who are distressed. I merely advised caution against yet another magic pill.
