Being female and the eldest, I was quite hesitant to take apart the mechanical things in our home as a child, just to see what was inside, and how things worked. Not so my brother, ten years my junior! From the high-fidelity stereo in its fancy 1960s console, to my father's golden D104 microphone as well as the CB, my brother could not resist. Of course, being his elder, I had to attempt to fix, then tell what the poor kid's curiosity had done to him again. And it was OK, while gathering up the bits and parts, to take a minute and check out just how things worked.
So yes, it was enjoyable for me to watch James May reassemble a lawnmower, a landline dial phone, and an electric guitar (actually, well, I've seen the innards of an electric guitar, growing up in a household where I was the only one allegedly devoid of musical talent).
