I'm 36, and have only been into folk music seriously for the last 4 or 5 years. From my own experience and that of other people I have spoken to, it is around this time that a number of us 'come out of the closet' as regards performing/participating in music (we always wanted to but were to shy & have reached the age where we are less worried about the risk of failure, and more interested in enjoying the music). It is also an age where we tend to have left behind (or been left behind by) the mainstream popular music & have more interest in traditional things in general. Hence there seem to be older folkies who always were, younger folkies (kids of the aforementioned), and the thirty-somethings emerging out of the woodwork. Kris
