For a really long time I didn't know how to snap my fingers. I figured it out during high school, and can now snap with all 4 fingers and even do it consecutively.
I still don't know how to whistle.
Is there anything you can't do?
Can't whistle. No matter how hard I try I can never do it.
Ditto op. I'm the exact same.
I can't whistle either. Also can't snap with my left hand, only my right.
I can't make bubbles with bubble gum.
