I agree that an 18 year old is not fully developed, but they have to be able to make sensible decisions by the time they are legally an adult, because you have no means of stopping them any more. At the very least enough sense to know when they need to ask for advice.

Heinlein is right in principle but its a big ask. can do quite a bit of that list, but I have never butchered a hog or conned a ship or planned an invasion. I am pretty sure I could pitch manure but finding out whether you can die gallantly is likely to be the last thing you find out.

I am, and one of my daughters is 22 and the other 17 so I have seen a lot of the process of growing up.
