How does it happen?
Is it a gradual transition to babushka or do they just wake up one morning and **BAM!** they've no teeth, grey hair, wrinkled face and a headscarf on?
All the Russian women I've seen are either children, hot teens, milfs or babushka, never anything in between.
I like to imagine they are like Pokemon, once they reach a certain age they evolve into babushka.
