I started later in life, after being a stay at home mom for 10 plus years. I went back to regular school and now I'm working as a Software Engineer. I need to look up more concepts and ask more questions but I'm getting there. It's a long road but one worth walking.
I've been a programmer for 27 years, and I still look things up constantly. Not just API details. Everything. If I was mainly doing things I can do off the top of my head, I would suspect I wasn't doing as much as I could be.

More compared to who else? And who is keeping count? I have found that the most important questions you can ever ask are "why/why not?". You can never go wrong with that pair.
Exactly. If you've found some success and a knack for it, that's really what matters especially if you can find job opportunities. Code speaks for itself, regardless of age and other factors. I've seen a lot of unexpected people demographic-wise succeed. It's totally possible.
