>Do some research and you'll certainly find -
I certainly DID not write that 'persons' was incorrect - I just gave my suggestion, so there was really no need to attack me in this way. It would have been better to write...If you would care to do some.. If you were to do some...not... DO!. (a command which must be obeyed)
As you know, I am a speaker of BrE, so 'people' would be appropriate in my case.
As for doing research on the subject, I will certainly endeavour to do that.
