Another way to attract the attention of your reader is to set some text in bold. Use bold
to emphasise important points; use italics or underlining to highlight words. However,
be careful not to overuse bold type, as whole paragraphs of text set in bold are hard to
read. Bold type creates emphasis because it slows down the reader and forces their
eyes to concentrate more carefully on the text. Remember, though, that if you slow
them down too much, they may just miss out the text as it takes too long to read.
