My brothers, for some strange reason, did not develop that ability. The second something goes wrong on their computer, they freeze, deer in front of a lighthouse. Everything from installing apps, to fixing wifi settings, to customizing their desktops, to updating their iPhones, is a situation that causes panic. These guys are otherwise very functional, and very educated. One of them went off to grad school the other day with a new macbook, and after already having one for 4 years, asked me to "set up" his computer, which consisted nothing more of going through the walk-through for new OSX users.
It is one of the most frustrating and mind-boggling things. You can often hear me yelling at them, whether in person or over the phone, "You need to figure out yourself! Just play around with the damn computer! It's not going to explode!"
