If you put your hands behind your head can you then….

[saxonyv]

touch your elbows to the wall behind/floor underneath (or just generally put them in that position so they are opposite your ears)

Yes can you?

Yes, why?

Yes and you definitely should be able to

Just tried and yes, I can.
What's the significance?

Unless you happen to have disability that prevents it. In which case "shouldn't" doesn't come into it, does it?

yes I can

Yes, why?

Or not?

I can't even put my hands on my head. I can't even touch my face with one hand.

So no, some people definitely aren't able to

Yep, piece of cake

I’d still word it the same way.

a healthy, able bodied person should be able to and if you can’t then there must be a medical issue you preventing you from doing so.

Yes but only just about with my left as had a frozen shoulder (so bad I had to have surgery and its still only about 95% of the way there which I am grateful for given I could only lift about an inch from my side the day before I had the op!)

Urgh my wrists are tingling now.

Yes, though not without it feeling awkward, but I have very tight shoulders from lifting weights and I don’t do the post-workout stretches I should.

Yes but i could feel the stretch a bit, in a nice way, across the front of my shoulders. Going to do it more often.

So you needed an 'unless' in your statement then

Yes, definitely can do that. Lovely feeling.

OP, this is mumsnet. If you asked if "can you tuck your legs into your arsehole" you would have a chorus of "easily", "and my arms", etc.

I can touch a wall, but if I lie on the floor I can't put both elbows down to the floor. I'm quite flexible generally so I don't know why... I also have had frozen shoulders though, and I wonder if this has affected them in a long lasting way.

I do see your point.
But, unless I'm completely misunderstanding this, it's a very easy posture to assume for an an able-bodied person (which I assumed was a given).

Yes, now that I have finally recovered from my shoulder injury. I wasn't able to for about 8 months so it's great to do it without pain again.

Please move to the sex board 🤪

Or maybe the original poster needed to put in exemptions from the question - to define if they wanted a general comparison of abled bodies or if they wanted a more general to include all physical abilities

But, unless I'm completely misunderstanding this, it's a very easy posture to assume for an an able-bodied person (which I assumed was a given).

I see a lot of older but able bodied people in my yoga & pilates classes who can't hold their arms straight by their ear so would never assume everything is so easy for others.

Sorry but I must be missing something? If I put my hands behind my head my elbows are pointing forwards so how would I be able to have them touch the wall behind me? If I extend my arms/elbows outwards then the backs of my arms/elbows would touch the wall? Is that what the OP means?

Yes, easily.
