Hi,
I’m inclined to say : “It’s a myth that we only use 10% of our brain”. Is that wrong?
Should it be "“It’s a myth that we only use 10% of our brain”. ? Confusing is the use of a plural after a possessive pronoun “our”. I’ve seen it used and not used.
“We should take care of our bodies by exercising regularly” or “We should take care of our body by exercising regularly”.
I assume the example is supposed to be “brain” vs “brains.” I actually don’t know for certain which is considered more “correct.” I think both are acceptable, but I’m not sure.
If the people all collectively own one brain (e.g., freeway drivers during rush hour), then it would be singular. For example: “We should do everything we can for our family” means you are talking to people who share a family, whereas “we should do everything we can for our families” means everyone should take care of his/her own family.
I disagree. The use of “our brain” to mean “the brain that each of us has” is not strictly correct grammatically but is acceptable as an idiom and commonly understood. It’s like a yoga instructor facing 22 people and saying, “Raise your left leg!” Well, there are 22 left legs out there, but it’s idiomatic.
In that particular case, the second example doesn’t sound right - the first sentence is the one to use (or “Your body is not designed to sit in front of the computer all day”)
I agree Mangetout. The second sentence does sound odd. The first one is fine. In the second one I can say: “Your body (not ‘our body’)is not designed to sit in front of the computer all day.”
Thanks all.

Agreed - and in that case, “Each of you, raise your left legs” would be quite wrong (unless the audience is a nonhuman species where individuals have multiple left legs. Dogs, for example.)
Google suggests that the “10% of our brain” is more popular (and was probably the original formation) but that “10% of our brains” follows a similar pattern of popularity but only started to be used ten years afterwards.
He uses only 10% of his brain
You use only 10% of your brain
But I have to say that I would say:
They use only 10% of their brains
So I would prefer:
We use only 10% of our brains
One other comment: the “only” is misplaced in the OP (called a “squinting modifier” since it can look either way). Yet another comment: It is indeed a myth and a silly one at that since the brain uses 25% of our energy supplies (when the body is resting) and the idea that we are wasting 90% of that is absurd. YMMV.
It’s not that leg or legs is wrong in that case, but the first should be “**Each **of you, raise you left leg”, not “All”.
Then the plurality of people matches the plurality of legs.
It’s probably not the best example, because in that context, “All of you” is more or less a separate thing - a call for attention that could be replaced by ‘Hey!’, or “Simon Says…” and wouldn’t have to agree with anything at all.
