Prince Philip health fears: How Duke's 'energetic' body language has quashed health fears

According to Judi, the Duke’s upright stance was that of “a much younger man.”

The body language analyst added: “He snapped to attention, standing as upright as a much younger man, and despite a subtle grimace of his mouth, he soon adopted his signature pose of the behind the back handclasp.”

Judi said Philip’s wide smile and “twinkle in his eye” may have “astounded” those who feared for his health.

She added: “Philip’s grin told us he was delighted to be making this rare appearance and there was a twinkle in his eye that hinted he knew he was astounding people who had expected the worst about his condition now he has retired from royal life.”
