How Much Are We Really Taking in All the Time?

A few days ago, i was having dinner with my wife. My kids were watching t v as we were chatting. It looked like they were completely engrossed in the programme. But there was an element of his mind that could hear what we were saying. I think it's really interesting when we think about how much we are actually taking in all the time. We may be hearing even if we're not intentionally listening. The brain is still taking on this information, and there's an energy related to that.
