It is not one reason, but many reasons why the hobby is dying. I heard a statistic about ski hills, they are losing 30% of old clients per year and only getting 15% first time clients that spend about half as much as old clients. In reality they are only getting 25% the amount of money as they were getting before. It does not take long before the client base is eroded to nothing. The under 35 year olds are getting their jollies free, and they do not feel like going to a massage place to pay for it from a babushka.
