I was put on time-out for 10 minutes. I will never forget. Ever.

I was just instructed on the definitive, evidence based, therapeutic dose for putting a child on a time-out.  Apparently (this is actually in my book), "1 minute per year of age, with a max of 5 minutes".  Anything over 5 minutes has been shown to cause life threatening pouting and rapid-response crayon drawings of meanie faces.
