You know you were born in the seventies if:
*Your first memory of a 'mobile' was sitting in a freezing cold outdoor classroom
*Wireless was what your Dad called the radio
*The words 'Beta-max' and Celnet mean anything to you
*You can remember computer games taking twenty minutes to load
*Swingball was your main summer sport
*You ever built or rode on a guider
*You remember health frame glasses
*An iPad (eye-pad) was something worn by the kid with health frame glasses
*You were ever cognizant of how many pleats your trousers had
*The words FINDUS, CRISPY and PANCAKES mean anything to you when combined
*The Hi-Fi was a major part of how your living room was furnished
*You ever rode a Grifter or knew someone who did
*Your first memories of learning to cross the road are dominated by 'Tufty'
*You remember Ted Rogers and 'Dusty-Bin'
*Shell suits were ever socially acceptable to you
