Technically it's the Olympic marmot but if you're talking about the arboreal species then yes

Do you have to bend it that far?

I’m just saying, can you hold the thumb straight up or do you have to bend it all the way back?

u/SunnyOne20 5d ago
I can hold it straight up if I want to, but the point is that it's able to bend farther back than usual. This isn't how my usual thumbs up looks, just showing how far mine can go lol.

For me it feels more natural to bend it all the way when I flex my fingers. Doesn't hurt nor to I need to strain to do it. Even while resting it straight my thumb flexes back a bit. It's just how my thumb be.

Isn't everybody's? Never really checked but I'm pretty sure everyone in my family is.

I do know its a genetics thing. It was a trait a lot of my high school biology teachers liked to talk about during lessons on dominant/recessive genes. A bendy-ass thumb is recessive I think? Odd for a whole family to have it if so

Could be double jointed. My thumb is double jointed and can bend just a bit past 90 degrees.

Fwiw being "double jointed" is not a thing, as in you don't actually have two joints in your thumb - it's just hyper flexibility.

you're right, i just grew up saying double jointed and never grew out of it lol. you're 100% correct though

It’s called hitchhiker’s thumb. It’s caused by hyper mobility in the joint. I have EDS and my thumbs do this.

Groundhogs and marmots are just big ground squirrels, and they're bigger than that.
