2 questions about identifying an Indigo person

hello, I have thoroughly and carefully examined the Indoigo children description and I have 2 questions for Indigo experts.

1 My daughter was born in 2004, she fits the description perfectly. My husband fits the description too, but he was born in 1961. Should he be considered an Indigo too? Are there any older indigos?

2 I fit the description too, BUT for one thing (which seems to be rather important though) : I have always had and have guilt /self-worth problems, and insecurity issues (although I am not shy), while indigos are said to be very self confident.

Opinions are welcome

thanks
