Allan Pease has been known internationally as "Mr. Body Language" since his book on the subject became a multi-million best-seller all over the world.

　　Allan started his sales career at age 10 selling rubber sponges (橡胶海绵) door-to-door after school to earn pocket money. He began writing and developing his own techniques of selling at age 18. By 21 he was the youngest person ever to sell over $1,000,000 of life insurance (人寿保险) in his first sales year and at 24 achieved membership in "International Top 20" for multi-million dollar sales - the youngest ever to do it. At 29 he was a manager and partner in Australia's largest Life Insurance Brokerage and was responsible for $103,000,000 of insurance sales in one year before becoming a full-time speaker.

　　For over 30 years Allan has taught others how to succeed. He teaches skills and techniques in a humorous way that people never forget. His addresses, books and videos are sought by business managers, Prime Ministers, TV presenters and stars. He has written six best-selling books and has appeared on TV and radio throughout the world including a TV and video series on body language which has been seen by over 100 million people.

　　Today, he heads his own Training Company and gives speeches in 30 countries. His client (客户) list reads like a "Who's Who in Business" - names like IBM, McDonald's and the BBC. Allan has given speeches for the army and navy, and at hospitals and universities.

　　In his classes, he teaches others to read between the lines of what others say and develop an understanding through "Body Language" signals. Dr. Blair Stone, from Macquarie University, said, "Allan Pease is hilarious. He makes his class very humorous. Plus I never realised that I can laugh so much while learning so much, and his address was consistent (符合的) with the high standards a university expects."

　　"Allan Pease can hold an audience for several hours and still be wonderfully interesting and entertaining. He does an exceptional job," said Tetra Pak from Master Builders' Association.
