My grandmother Klara could twist her tongue in a tube from both sides. I’ve never seen anybody else do that and I can’t twist my tongue like that even a bit.
The only person I know who does it exactly like my grandmother Klara is my daughter Klara. Who never met her great-grandmother.

Can N do it? It’s apparently a genetic trait. I can do it, and so can both our daughters, but my husband cannot.

No, nobody can except my grandmother. We definitely have the good genes. 😁😁

I can do it, my brother too and a lot of kids when I was one.

I always thought everyone could do this. How odd. How about wiggling your ears? I know that only a handful of people I know could do that.

I’m not sure we are talking about the same thing because I looked it up and it seems that only under 5% of people can do vertical double-side rolling.

No that is what I was talking about. My whole family could do that as far as I can remember, most of my friends from what I can recall too. I’m not sure about that 5% of people. Possibly low survey count?

I think I need a picture of this tbh

Apparently the genetic angle is more complicated than I thought (and this article repeats a statistic I’ve seen elsewhere, that 65 – 81% of people can do it): https://www.bbc.com/future/article/20180130-do-you-inherit-the-ability-to-roll-your-tongue

Yes, the U shape is what most people can do. But I’m not talking about that. I’m talking about a genetically rare thing. An actual roll.
My whole point isn’t about tongues but about the strange roads if heritability.

Oh, I totally misunderstood — thought you were talking about the U.

Same. I did a google search the first time, and it was showing that as well. Heck vertical double sided rolling sounds exactly like that.
