Actually I will defend Dr Dance all day long. I think he is a bit of a hero.
First - He can actually dance. I know he dosns't look like a dancer but anyone who knows about dance can see that he really does know how to and in a multiplicity of styles
Second - He is a bona fide psychologist and reseach academic. He does know his stuff and doesn't try in normal life to liken people to dance etc
Third - And most important he does really valubae work which is about using dance to improve the lives of people with Parkinsons. Parkinsosn is a hideous disease which leaves someone who gets it unable to control their body properly for maybe 20 or 30 years. He has studied the way the brain works in dance and used that knowledge to help suffers improve their balance, speech, movement and above all mental well being. It really is quite special what he does.
Big Brother appearances pay a fee whch helps fund the research.
