Yeah I never brought it up because who's sees my hands?

So you have groups of 4 knuckles? Thats actually pretty cool. Almost like having the ring and middle finger glued together, wouldnt expect that to be too different (though i am curious 🤔). If you wanted, im sure you could get (or build) some cool prosthetic that is close to having 5 independent fingers.

Do you really have four fingers on one hand? That's mental, I've never seen that before.
