A world witho0ut hobbies? I'll give you my experience... In 1987, while with the U.S. State Dept, I was assigned to Havana, Cuba. I shipped my entire model building outfit; bench, paints, airbrush, compressor, etc., etc., and 10-12 kits to keep me from going insane down there. As with any foreign diplomat, our household affects were subject to inspection upon arrival by Cuban Customs authorities. When they got to my hobby supplies/kits crate they went a little funny. Since they were all born after the 1959 revolution they had never seen a model kit. I had to open up one of the F-4J Phantom kits and with my less than adequate Spanish attempt to explain that the kit was a scale model, not a 1 to 1 version. What really blew them away was the little bottles of Testors paints. Paint of any size/version was nearly nonexistent in Cuba and those little paint bottles fascinated them.
As time went on and I began and finished models I would notice that things had been rearranged while I was at work at the U.S. Interests Section. The Cuban DGCI (Intel outfit) had free access to our houses. Nothing would ever be taken or broken, but they would let me know that they had been in the house. The MiG-29 I did down there got moved around quite a bit! I often wondered what their intel file on me looked like.
About the only hobby the Cuban people had was supporting Uncle Fidel. Believe me, a world without hobbies is not a pretty sight.
