Speech is not an easy thing to master, and a baby's passive vocabulary (the words he can understand) is often far more developed than his active vocabulary (the words he can use). Long before he utters his first word, a baby has specific needs and wishes to communicate. Studies have shown that it is easier for babies to reproduce...

They will ascertain something about the corporate structure, the VIP's, those employees who have won awards, etc. This gives a speaker an "insider's edge" when he or she stands before what is otherwise a roomful of strangers. By...
