Fast or slow reader?

Many people consider me a fast reader if a book in three days but I consider people fast readers if they read a book in a day!

So this question just stumbled into my mind and it is how do you define a fast reader? And do you think you’re a fast reader?

Do you think reading a book in a week is fast? A couple of hours? And what about a slow reader?

Please leave your answers below because I am really interested to see how I fit in the spectrum.

I’ll write soon.
