Here's a scary thought...
Stupid people are reproducing. Yes, and they are doing it faster than normal people, too. That's why stupid people outnumber intelligent people so badly. So, as a public service, SailorN1 has decided to give you something to think about --
* Stupid people breed sooner -- stupid people usually start reproducing between the ages of 12 and 18. Don't laugh. I've seen 12 year olds have children. Pathetic, I know. Normal couples tend to breed between the ages of 20 and 35.
* Stupid people breed faster -- stupid people can somehow produce 2 children in the time it takes other people to produce one.
* Stupid people breed more -- for every normal couple that has one child, stupid people tend to produce 3 to 6.
