I was just thinking of all the crazy stuff that Iaroslav's parents would have lived through. Stalin's famine (his mom would have been a peasant on one of the collective farms), WWII along the eastern front (Ukraine was occupied and a battleground, and his father was at Stalingrad. Come to think of it, it's possible both of them were soldiers, however unhappily), then the entire Cold War ...and raising Iaroslav, natch. :P
I have a Ben Franklin quote written in the front of my favorite Ukrainian history book "Happy that nation, fortunate that age, whose history is not diverting." The Chinese curse (it's English, but whatever) "May you live in interesting times" fits too.
I've never done the math on Slava's parents, but it's a real possibilty they were born shortly before or during the 20s famine.
