I'm including identifying and backing up any data files in that "couple of days". And actually, I've already been working on that all weekend, and still am working on it. The actually "clean and reinstall" probably won't take longer than a few hours (if all goes well). But with me, "if all goes well" is almost never the case. Inevitably something unexpected comes up that prolongs or complicates things. It just happens. It's why I rarely attempt to fix anything more complicated than screwing in a new light bulbs or replacing batteries.

If future generations are to remember us with gratitude rather than contempt, we must leave them more than the miracle of technology. We must leave them a glimpse of the world as it was in the beginning, not just after we got through with it.
