OK here it goes....I have a BSc in Geology, a PGDipSc in Ec/Mining Geology and a MSc in Astronomy/Astrophysics. I was a geologist for 15 years before I had to give it up because of my own illness and having to also look after a terminally ill father. I have been published in both industry and academic journals, twice altogether, as a geologist. I've also been an amateur astronomer for 40 years. I think there's some mileage in that
