Today this text + hidden text was added by user:Keraunos. I have heard very different statistics. This statement must not stay long without source.
One study indicated that about 80% of the population are primarily morning people, 17% primarily night people, and 3% primarily afternoon people. [Hidden text: Please do not delete this! If you are a psychology student, please try to find the reference for this. I heard it on a radio program.]
I just deleted the abovementioned phrase since it's 6 motnhs after ti was posted and tagged and no sources have been provided yet. If you get a source feel free to add it again. Veritiel (talk) 13:01, 17 December 2009 (UTC)[reply]
