Hmmm, I can see myself reporting on random trivia now that I'm watching that trivia program but anyway, according to the Japan National Institute of Population and Social Secruity Research the average number of kids born per couple is 1.2. Computing out, if it says the same there will only be 27 people left in Japan in the year 3000.
That part if the show ended with "How about doing your best to help solve this problem tonight?" 😛
