I was 6 when I first built my own model. That was in 1973! And there still was a model building interest amongst my friends and I all the way up to the 80's. After that, I really started seeing a decline in new builders and most of my same age friends started getting replaced by guys at least 10 years older than myself!! Some of us stuck to the hobby and some faded away. Some of my friends say that they miss it and would like to build a model with their kids, and I have even given them kits to do so, but eventually they fade out again. Yup we are truly a breed that is thinning out, and it appears sadly, rather quickly.
