how was anime able to distinguish itself from animation in other countries?
I've been into anime for awhile now, but something that I've always been curious about is why Japanese animation was able to separate itself to be considered its own medium, unlike animation from, say, Russia or France?

Is the Mega Millions ($500 million jackpot) worth buying tickets based on "pot odds"?
In poker, you make decisions to call based on pot odds. Based on this concept, it would make statistical sense to buy a ticket assuming there is only 1 winner.
