Actually, you can study that.
My brother and his wife had a couple of foster kids, sisters, for a short while.
About a year, when they where 13 and 15.
It seems they bonded so well my brother ended up paying for a large chunk of their lives for the next 10 years, including college.
One of them studied some type of ecological major.
She spent a lot of time in the woods, was camping, was very happy, and got college credit for it.
She changed her name from what her parents gave her to "Sky" at that point.
When she got married, it was in the middle of the woods on a mountain, way out west. I believe my brother paid for a bunch of porta-potties for the event.
