I'm 41 now and playing in a band for a few years. We all enjoy it and making our own songs. I'm not a great guitarist but lately i took some lessons and my technique improves rapidly, that's something i must have done 20 years ago. If i could do it all over again i start with the lessons as soon as possible. I did not get all the support from my family and when i moved from home my life changed, in my work as a nurse i worked at inconvenient times, it was very hard to join a band, also we've got three kids, now the kids are growing up and i've got a regular job and time to join a band. I enjoy it and like to play live, like an old dream still come true. Maybe sometime later then i really wanted, but if i become 70 years old i've still got 30 years to go to play and practice.
Your never to old to rock and roll.
