Learning, we are often told, is a life-long endeavour, and I certainly agree. And with smart phones and Wikipedia we are able to keep learning all sorts of stuff, some of which might actually be correct.
If we want to be honest however, most of our learning, at least the important life lessons, happen when we’re younger. When we’re very young we learn things like not touching a hot stove or the converse, putting your tongue on a metal pole in the middle of winter is not a good idea (although I’m not sure why I needed to learn that one more than once – but by the third time, I got it down).
