A few items (I'm 68):
1) All airplanes were piston engine prop driven (1950s). DC-3, de Havilland Dove, DC-7, etc.
2) Radios and TV had tubes, took 30+ seconds to warm up (even those in cars - those that had them - they were options). We had to take them all out and check them on a regular basis. Most grocery stores and hardware stores had tube checkers.
3) No power steering, no power brakes, drums all around.
4) We were trusted to walk into a gun store, pick out what we wanted and walk out with it after paying. Just like buying a toaster.
5) Post cards and hand written letters were common forms of communicating and staying in touch.
