Johnny Ball has insisted that the Strictly Come Dancing judges may seem harsh in the criticism, but they are actually very supportive of all the stars taking part.
Johnny advised this year's contestants: "Just enjoy it. The dancers are so incredibly attractive, and the attractiveness is in their sheer physical fitness. That's why the programme is popular, and the judges almost echo that. They can be very caustic in their summing up, but in actual fact they love the fact everyone is having a go."
Meanwhile, the veteran presenter - who hosted science progammes for children - revealed his frustration about the repetitiveness of modern TV shows.
Johnny revealed: "Repetition drive me mad. You watch any programme and they say, 'What we're going to do in this programme is this, this, this and this'. They show an interview as a taster, then when you get to the interview, they say, 'There are only 24 per cent of people doing this.' Cut to the person, 'There are only 24 per cent of people doing this...'. So that's the third time they've told you!"
