Do you need data that describes characteristics of people?

For example names, addresses, dates of birth, height, a recording of their voice, a picture of their face, imaging, hair colour and character traits, etc. Or confidential information such as a health condition. These people can be real, made up, living or deceased.

Yes, I need data that describes people

No, I do not need data describing people. I need data of the events in which they participate

This could be appointments, treatments, diagnosis that does not reveal who the individual people are.
