I know as an actor there is a certain liberation auditioning for a role that has no beauty requirements.
I had a great time in my youth and I still feel youthful. I've no desire to look as though I'm in my 20s.
I cannot say how strongly I object to people using other people's writing as research. Research is non-fiction, especially for horror, fantasy, science fiction. Do not take your research from other people's fiction. Just don't.
