"Όλοι οι άνθρωποι χρειάζονται αίμα."

[jeanprendiville]

" All humans require blood" as an alternative?

Thank you again for a good sentence.

...not gonna lie, I had a moment where I saw όλοι and my brain registered όχι, which makes for a very different meaning.

[SleepyTinman]

"Everybody needs blood" should be accepted

[jaye16]

Yes, it has been added. Thank you.

[Lng52-._]

Can you omit "οι άνθρωποι" and just use "Ολοι"?

[jaye16]

That would change the meaning since it refers specifically to people, not other animals.
