I don't know if I am the only one, but there is a male with rather patchy GREY hair, that has it all his life. It makes it difficult to tell how old they are, and I'm forever chasing after them to find our who is how old. The grey-haired girl with chin length straight hair is another one. I never know how old she is, either. She DOES turn a beautiful silver when she reaches 55, I will say that. However, the male looks the same from cradle to grave. If you have more than one, do you also have to check his age?

Yes, I have some villagers like that! and some fiends too (in the real life), my ex-boss (a female, director of a theater band) and my brother in law. They were grey haired at 25/30 years old!! (in French, we say "pepper & salt" hair )

I have had villagers like that too.
