A user will typically view information for around 7 to 10
minutes. While it's wise to keep within that limit, it's ok
to go past that if you execute correctly.
Short information = 7 to 10 minutes
Longer information = Longer than 10 minutes
If you have to present information that is longer than
the ideal 7 to 10 minutes of attention, introduce breaks
or novel information that will give the user a fresh
starting spot
