Do you remember in what circumstances you absorbed some shreds of the knowledge you possess? I in many cases am able to vividly recall the situations in which I got to know this or that, including how old I was at this moment and from where I got this knowledge. For example, to show what I mean by this, I remember the moment I was in the common room of my elementary school, at the age of 10, maybe 11, reading "Flame" - a teen magazine, the issues of which were laying on the shelves in there. Old issues, already at least 10 years old, at the time when I was thumbing them; my peers. On the first page they had a section entitled: "For the curious - curious matters", containing, as the title promised, many curious details on stuff, trivia. I remember it was from where I found out back then that the tip of the nose is the coldest point of human body (just 36 degrees Celcius) or that most inhabitants of Łapy http://en.wikipedia.org/wiki/%C5%81apy have their last name Łapiński. Do you remember such cases?
