If I had a penny for every time I’ve wondered what BB is thinking, I’d be able to buy a new pair of Jimmy Choos by now. And maybe even a matching bag. Here she is (pictured) in the paddling pool at granny and grandpa’s house this weekend, the master of all she surveys.

What on earth was she thinking? Is it even possible to ‘think’ when one hasn’t mastered a language yet? And was she in fact feeling, rather than conducting an internal monologue about the sights and smells around her? I’d love to know.

Apparently a child has around 100 billion brain cells at birth, and around 50 trillion synaps connecting those cells. By eight months this has increased to 1,000 trillion synaps, but by the age of 20 the number of synaps has decreased to 500 trillion. So you could say she’s in her prime. Unlike me, and probably you, which is alarming stuff.

Which has got me thinking about my poor withered brain cells. Is it possible to stop the rot? Is it possible to reverse the decline? The more I think about it, the worse it seems.

Probably best not to think about it. Probably best just to carry on wondering what someone else is thinking instead…
