@EllenInEdmonton I definitely would not refer to other adults as girls/boys. This only applies to myself.
For me it extends past just feeling "young at heart."
I've given a lot of thought recently and I think it's more of a feeling of being underdeveloped or stunted that is rooted in trauma and neurodivergency.

Sorry to hear that trauma has impacted your sense of being fully developed. I hope that you can find suitable help to work through some of that. EMDR therapy can be super helpful for reducing the trauma reaction. There are costs and benefits for every stage of life. I loved feeling invincible in my earlier years and I like feeling seasoned, now that I've experienced a lot more of my life. Hope you find what works for you.
