Aloha once more!
Sarushka -- thanks for the identification of Carol I to Nicholas's left -- I knew you'd have an answer for me and you didn't disappoint!
So that was Marie of Romania's father-in-law?
I too don't know how many cigarettes Nicholas smoked in a day, but since it is always so prominently mentioned in any biography or contemporary description of him, I'd bet that it was a lot! (Plus it seems like he is smoking in almost all the video clips that I have seen) Sun damage can certainly age you -- I live in Hawai'i (land of perpetual sun!) and I can certainly testify to that!
As far as dental problems go -- I try not to think about just what his teeth might have actually looked like! At least in his later years.
One of my absolute favorites -- I love seeing him with his dogs
