brain’s higher reasoning facilities to sleep? Sure, it can happen,

Internet
guru Guy Kawasaki has long advocated something called the 10/20/30 Rule,
designed to encourage you to make smarter, sharper, more effective
presentations. Here’s what you need to know:
10 slides. Guy says this is the optimal number of
slides because humans cant process more than ten concepts in a single

20 minutes. The whole pitch should take no more than
20 minutes. If you book an hour, that gives you nearly 40 minutes for
questions.
30-point font. That’s the smallest your text should
appear anywhere in the deck. If you make the text smaller, you’re going
to be tempted to just pour your whole narrative onto the slides and read
from the deck — which is a fatal error which will cost you your
audience’s respect and attention. [via ReadWrite]
