For the over 30's in the U.K...do you ever think about retro food?

Do you ever think about food from the 70s or other era's? Things you wouldn't eat now...like tinned marrowfat peas...or Cambells meat...or Fraybentos pies? Yuk! I bought some marrofat (processed) peas today and they were the weirdest thing I've tasted in a long time...
