learning or doing anything "changes your brain". that's how learning works.

i hate this phrase and how it's generally used for scare-mongering headlines.

First, this is true - learning or doing anything does change your brain. This article isn't talking about just that.

I personally don't think it's meant to scare-monger, either - although I'm sure opinions may differ on the subject.

What is unique about being a dad is having a living breathing creature depend on you. There are hormones exchanged. AND you're learning and doing something. AND you're remembering (and having to deal with) your own childhood memories. And realizing that in your memories, you were the kid ... now you're the adult. It's different.

This is not mere learning, must have some kind of pre-wired special mechanism because it's very quick and very strong.
