Why is there a guitar on top of this page?

There are a number of reasons, but here's three:

1. Studies consistently show that engaging the brain with something new, whether music, a language, or an activity, are significant for maintaining both your physical and mental health.
2. Because they're really hard to play well!  I'm using my left hand, learning to read music, and enjoying the frustration that comes with being really, really bad at something!
3. Because even when you look at the detail, it's still a beautiful instrument!

Okay, where are you going with this?

I'm pushing myself to learn something new, something beyond my limits (where I'm really uncomfortable) in an effort to keep myself sharp.  So what are you doing?  I'd like to hear it!
