Today's questions:

1. Does the myelin sheath development also apply to more purely mental abilities like reading and comprehension, or the ability to imagine and come up with inventive solutions to a problem?  For example, how much can learning and practice be helpful in growing infants and children? Will a baby that is spoken to for 5 hours a day learn to speak significantly faster than one exposed to only an hour of language a day? Or are parents kidding themselves when they spend so much effort to give their child an edge in cognitive development?

2. I'm a private person: I cringe when people air their dirty laundry or have what to me are very private conversations in the facebook comment section. I don't signal affiliation or loyalty the way most people do, and tend to minimize advertising even when it would be seemingly beneficial: I recall declining someone wanting to write an article about me back in high school because "it's nobody's business". I realize I'll always be like this, but the way you and Geoffrey Miller talk about advertising opened it a new perspective. Do you think I'm missing out, and if so, how could I improve where it matters?

3. How do scientists go about measuring genes? How do they identify and associate them with human behavior? Is this something they can see with Petri dishes and a microscope? What would a behavioral scientists day look like?
