neat,very cool model as always. and you are right there is a steep drop off at the line of present day adults under 40ish. if you are younger than that your knowledge of the world around you,history, science,pop culture, etc.etc.etc.etc.is very sparse. one of my jobs is a waiter at a classy italian ristorante. one of the kitchen help(a 25-28 yr old dishwasher) made a comment about a new bus boys haircut saying he looked like that adelle hitler guy.when i spit my water out laughing he said you know that guy in that war. i says ww2 and he replied i dont know i guess. i seems anyone especially below 30 is really practically where i was knowledge wise when i was around 10 or 11 years old.they cant spell or add hardly its really sad.
