About the Author
Mark Whitehead started his career with a brief spell as a teacher before finding his vocation in journalism. He covered education, HR, management and general news for a variety of publications before specializing in purchasing joining Supply Management as deputy editor. The baffled looks on people's faces when he tried to explain what his magazine covered led to the idea of writing it all down in a book. He strongly believes that nothing is too complicated to be explained simply, which is one reason why he became a journalist and not a nuclear physicist. The other is that he dropped sciences in the fourth form. He lives with his wife and young son in north London, where he plays a variety of musical instruments and beats the congestion charge by cycling to work.
