I’m not sure trust has a age category. The fact that you stated ages makes this question interesting to me. I can only share my own experiences and I am 50. I always had little reason to trust. Since my primary caregivers, my parents were not trustworthy either. Yet I always decided to trust. These days I trust less, learned from experience. Life is our teacher. I am choosing the life of a Hermit, so more and more these types of things will no longer concern me. And this is the best feeling I have ever felt. I gave it my best shot, it didnt pan out, so Im out of here.
