I think i'm losing my mind

Seriously why am i sitting here in work , the radio is on 95.1 and its Wednesday so you know its all 80's of which I'm not particularly fond..yet I'm singing every song, bobbing my head, hitting the desk as my drum, and the occasional air guitar...i have seriously lost my mind people....I'm gone clear...the scary part , i know all the words. Is this the effects of internet deficiency syndrome?
