As an adult beginner on the fiddle, I heartily endorse your idea to take it up. I started at the age of 62. I'm having a great time with it, although, as one experienced fiddler told me, "It's not an instant gratification sort of thing." On the other hand, if you put in the effort, it can be very gratifying.
As someone up thread mentioned, the fiddle is not a singer's instrument. I've watched my teacher try to sing while playing, and I have never seen such focused concentration on a human face. The fiddle really takes all of your attention to play well.
I'm four and a half years in and intend to keep playing until I can't. Do find a teacher who knows the kinds of music you want to play. And find a CD called "Violin Sing the Blues for Me."
