Genetic? Truly? Wow. No one in my family ever even mentioned it.
I guess they didn’t know that they could. I just tried it one day, and I felt the little twitch. I was amazed.
I can do it with a thin forked branch, but I have never tried it with wires.
Thank you, sir, for that information.
In my family, it comes down from my dad’s side.
He showed me how to do it with the wires, and it worked!
Now, I’ve polled my family, and my siblings and their/my kids can all do it (so far), but none of their spouses.
