Sometimes I like to take what I call decade holidays, they are holidays, where, for a few days or a week, I'll only consume media from a particular decade and I'll try to do things or use technology that was available in that decade (sometimes I'll also try and dress and/or cook a bit like its that decade too

)
Its fun, and after a few days living in another decade you get a new kind of understanding of its ideas and its moods; and when you travel back to normality, you can compare and contrast things from your time with your decade holiday.
It's also been a really creative creative tool for me over the years, for example I started my site after a 90s decade holiday, but of course you can pick any decade if you have enough media and interest related to it.
Do you take slimier mental holidays? How do they go?
