well, for starters, let's redefine the term "gigging"

There is definitely a difference between posting a recorded song to youtube and playing in front of a live audience.

If you want to try your hand at the latter, consider joining one or more of the streaming sites. You can play to live audiences from the comfort of home, get immediate feedback on your performance, earn money, and avoid the one thing that makes gigging unpopular with older folks: carrying heavy gear in and out of buildings!

Lots of older musicians are using streaming sites these days. Costs nothing to join, and it can be a lot of fun... just ask the people who are currently doing it.. Danny, Kemmrich, Josie and some others I can't think of at the moment.

I think playing music to live audiences is an excellent way to keep the ol' synapses active
