It's not my strong suit but I'm glad I checked it out. I'm always interested in what's going on, sure. But I think there comes a time when you say enough of the new doodads and whatever the new stuff is. After playing for 50 years you've got to kind of find your strengths. And I think my strengths are in playing a song well, and being able to improvise within a set of changes. So I'm not concerned with experimentation anymore.  I'm just trying to get the core of what I do best.
