I actually found these chapters to be very interesting when they were describing the different tones portrayed by the different fonts.
When it comes to fonts that describe me both personally and professionally I would end up choosing the same fonts. I tend to choose fonts from the Sans Serif family mainly because they have a clean look to them. With other fonts there are often cupped serifs on some letters. Whereas with Sans Serif, which literally means “without serifs” there are no serifs just “squared off terminals”. Another reason I often choose Sans Serif is due to the spacing. I like the fact that the spacing of letters is close enough not to have a bunch of whitespace.
While looking at some different fonts on the Internet I came across an interesting article which talks about spacing at the end of sentences. This relates to fonts because if a font has more spacing between letters it may require that extra space be left between sentences so the reader knows when they have reached the end of a sentence.
