One of the things I love about playing music is that there are no barriers! If someone gets excited about playing and learning, I enjoy making music with them, no matter their age, sex, race, etc... it is a unifying language! Besides, the new generation of audience generally care little about image, (though there are exceptions), they are are much more interested in good music, and if you make it in your 60's, 70's, etc, that's fine with them. I used to work at a high school, and a whole lotta kids used to come see a band I was in with fellas their parents ages or older. Keep playing!
