This may sound strange, but it's true. If you smoke and/or drink lots of coffee in the morning it affects the muscles, including those in your tongue. It actually retards the movement (speed) of your tongue.
I speak from experience. By about noon my early-morning feeder call sounds more like rrrrrr, rrrrrr, rrrrrr, rrrrrr.
Was there a study done on this? Don't know. That's what happens to me!
Told ya it may sound strange.
Any help?
