I whistle. A lot. So much so that I'm concerned about getting "whistler's lines" around my mouth similar to the wrinkles smokers get from pursing while puffing.

I used to sing a lot. Then, for a variety of reasons, I lost my voice a lot. So necessity being the mother of invention -- the necessity being a way of musically expressing myself while toiling away on this task or that -- I started whistling. And continue to whistle ... in the car, while doing chores, while trying to annoy the cuss out of my cat Isabel, who thinks she's obligated to sing along every time I strike up a tune but makes it very clear she resents the obligation.

Yep, I'm a whistler. But I got nothing on world whistling champion Geert Chatrou:

Wow!

One of these days I just might shoot a video of my duet session with Isabel. YouTubers eat up that kind of thing.

In the meantime, I'm considering writing Mr. Chatrou for his secret on reducing whistler's lines; he's clearly escaped the plight of the pursed-lipped. So far.

Have a happy Saturday. I hope you'll whistle while you work!

Today's question:

What's your favorite tune to whistle?
