The Personal Analytics of My Life

“OK. So email is one kind of data I?ve systematically archived.
And there?s a huge amount that can be learned from that. Another
kind of data that I?ve been collecting is keystrokes. For many

“There are all kinds of detailed facts to extract: like that the
average fraction of keys I type that are backspaces has
consistently been about 7% (I had no idea it was so high!). Or how
my habits in using different computers and applications have

documents (including blog posts). But at least at an overall level
things like the plots above look similar for keystrokes and
email.”
