Ever too late to become an RN?

Hi, I tried to search if someone had asked this before but I couldn't see anything. Please forgive me if I'm mistaken.

For some time now (think, years) I have found myself increasingly drawn to the idea of working in Palliative care. I don't really know what caused it, but I just have this growing sense that it's what I should be doing.

I'm early 40s (headed into mid..) I've been working in my current field for 20 years. It's not related in any way to healthcare, but I do have all the necessary qualifications to do a postgrad/accelerated Nursing course.

Perhaps there's an RN in this community has experience of entering the profession at an older age? I would love to hear your perspective.

And for those of you still studying, are you balancing it with childcare, or perhaps retraining?

Thanks in advance.
