I know some of it has to do with raising a family and as time has gone by and the kids are on their own (so to speak) it is easier to do something for your self and in some cases splurge. "Life is not getting any longer and if I am going to do it, better do it now". I know I have said it before but I am supported in the hobby by my wife so it makes it easier. I hope the numbers that are reported in the younger age group are what I am describing or the hobby may have a rough time in the future. But then again less than 30% of the viewers have responded.
