"having kids makes parents thick"

thanks to ihmissuhteet blog i finally found out the reason why i never want to have kids:

the sun newspaper online: "in a five-year study, they checked the iqs of couples who were planning to start families, then repeated the tests six months after their first child was born.
they found the intelligence levels of both mums and dads dropped significantly.

and they particularly lost the power to think objectively.

study head dr hosung lee, of america's indiana university, said: "it explains why parents think their kid is the smartest in class or the best athlete, even if that child is as dumb as a box of rocks or needs a calendar to time a 100-yard sprint. "

"the research team tested 173 couples. ALL fared worse on the second iq test — and most dropped 20 or more points.

that’s one fifth of the average iq of 100. "
