Sorry, didn't know you were a vet or an acknowledged expert in physiology. I apologise. As you indicate that you are, then, sure, you can sit beside me in the dentist's chair. I may wish to check you qualifications first, however!

Like your friends - I am a self-appointed expert on the nature of the pain that others have to endure. Like the trust you place in them - you rather have to also place your trust in my claims .....

As for checking my qualifications first. I am reminded of a cartoon where the chap sat down in the dentist's chair and held the dentist's testicles in his hand and said - 'this isn't going to hurt
ME - is it?
