Duncan Garner talks so fast these days that for an older person it is very difficult to hear everything he is saying. This morning his pace of speech can fairly be described as "gabbling". I know he has a lot to cover but there is no point if his audience cannot hear it all. On the contrary, Amanda, Mark and Aziz all speak clearly, they enunciate their words and they speak at a reasonable pace.
I used to work in New York where people do speak fast, but Duncan leaves them in his wake.
