LONDON (AP) — Actress Emma Thompson says dancing with Prince Charles is "better than sex."

Thompson makes the comment in a Time magazine feature on the 64-year-old heir to the British throne.

Charles tells the magazine he has had a lifelong desire to "heal and make things better."

The prince, who backs a host of charitable and environmental causes, said he feels it is his "duty to worry about everybody and their lives in this country, to try to find a way of improving things if I possibly can."

He also reveals that he recently staged a rehearsal to help teach his son, Prince William, how to host an investiture ceremony in which Britons receive knighthoods and other honors.

William presided over his first investiture at Buckingham Palace last week without any problems.
