I am sure I can come up with a list of 50 year olds who have killed people if this is what you are asking..and even some who are grandmothers with grandchildren....
If not, then yes, "I think"
What about Tookie Williams? He is a nobel laureate? (I may be mistaken on this but you get the point). So if you refer to him as a prize winning author, sounds real good. If you refer to him as a fiend who slaughtered 4 people, sounds a bit different.
Does make the point clearer?
