Brilliant, beautiful, amazing. But...
I know it's a small thing. But I've never, ever met a doctor with loooong fingernails... and I've known a LOT of doctors. I know - she's a psychiatrist. She doesn't do medical exams. But I've never seen a psychiatrist with nails that long, either. It's just not considered professional. I've certainly never had nails that long and I'm a doctor.
In fact, my casual observation has been that women in high career levels don't have those long nails. The higher the position, the shorter the nails and the less the jewelry. (And CERTAINLY no shaved, penciled-in eyebrows or big hoop earrings!)
I never saw research about this but it is something I have noticed.
