Audiotapes. Walkmans. 
Do they still exist? Yes, apparently they do . For some kind of reason, I think that’s pretty amazing. As a seventies kid, I was one of those who had a ‘Walkman’ and went through puberty buying too many blank tapes and too many records. And then the CD boomed, and I remember that was only because everyone was in love (or got in love) with the ‘jewel boxes’.
So 20 years later, after I bought my first Walkman (from the Erres brand, and yes, those things were huge then: that’s why they had a handy beltclip) and carrying it along with me to school, I wonder where time has gone. Slogans like ‘Sony Walkmans keep us walking’ have been replaced with ‘Rip and Burn Forever’. Nothing beats growing older.
