babies and brainpower

from The Observer: "rearing a child is so challenging it stimulates brain activity. Having a baby is 'a revolution for the brain', says Dr Michael Merzenich of the University of California in San Francisco. The brain creates cells that thrive the more they are used and the emotional, novel experiences of childraising provide the most stimulating use of all."

This is part "Department of Duh" and part "Shit, now I can't use motherhood as an excuse for being flaky and lazy anymore!"
