If grad school was paid for but not for nursing

If YOU were in your 40s & burnt to a crisp on nursing, and someone else was paying for you to go to grad school, what would you study?
NOT nursing related. Healthcare related.....okay.....just not nursing related. Curious to read responses.
Sure IF it is something that interests you.

I am very interested in completing an MS degree in human resource development. Either that, or I would earn an MBA with a specialization in human resource development. I would rather pursue an educational path that would enable me to minimize or eliminate face-time with patients and family members.

I'm interested in an MPH (Master of Public Health). I've always enjoyed looking at health from a population based perspective.

Hands down, nutrition, focused on disease prevention and mgmt.

MBA Healthcare Administration

I'm doing an MBA in Healthcare admin, starting in March. I don't see anything interesting in the future for me (also in my 40's) that I'd use an MSN for - at least an MBA might help me in unrelated ways - and I just find the subject material more interesting.

If grad school would lead to a job other than nursing, then why not?

Informatics or Healthcare Administration.
