Great topic!!
Been building since I was a kid, my Dad was a big supporter of mine as a kid through my teenage years. He passed when I was 19. 42 now and building pretty regular now, through my 20's and 30's did not get much built...as others have said life got busy so hobby time was limited. What inspires me is my fascination of automobiles and modeling opens up all makes to me and as I get older I find it very relaxing as well.
