I can’t really whistle. It’s not completely impossible, though I thought it was for the longest time. Within the last ten years or so, I managed to whistle a little, but not regularly or well. However, sometimes kind of. Sometimes when I’m riding along in an elevator, which is pretty often given my usual movement patterns, I practice.
I don’t know why, or why I care.
Whistling seems important. I’d like to be able to do it whenever I want, instead of just kind of sometimes. No idea why I can do it on rare occasions, but then not the rest of the time.
Oddly, whistling on the inhale is easier.
