Surely it all depends on what you're in it for?
I'm closer to 60 than 50, I have a career (most of which is now behind me), and absolutely no wish to start a new career as a struggling, under-appreciated musician!
For me, music is about fun. I play in as many bands as I can handle - all in my spare time, of course - and in as many ways as possible. And it's fun.
In the (astonishing) amount of time I've spent on Basschat, I've come to realise what a broad spectrum is out there, and how many people are unhappy with where they sit on that spectrum.
I'm just delighted to be where I am ...
