      that’s an effect of the demographic transition. society stopped having a dozen kids each so maybe three or four make it to 20. now they expect all (or nearly all) to survive to adulthood.

            Alright , alright, alright. What’s the fastest disease we can spread to kill children? We need something where if one kid leaves a room, another kid can walk into the room an hour later and catch the disease. Something that can infect a whole school basically at once.

            Any ideas? What’s the fastest spreading disease you can think of?
