I have a theory.
As I have been working with people and their computers for over 10 years now, I have had a small but memorable percentage of users who cannot get a computer to work for them consistently for love or money. Christa, Valerie, Dana, Denise, Alexa and Eric know what I mean.
It's the most bizarre thing... you could give each person a new computer every six months, and somehow each person's system will slow down to a crawl, have the most un-reproducible errors, have bugs that disappear when I sit down at their computer, with no discernable pattern. Except that it is, simply, THEIR computer.
I would say it's about 1 in 20 people who have this kind of random, inexplicable dysfunction. It's not a dislike for the technology - in fact, some of them have been my most ardent users. But Technology seems most reluctant to serve them!
Since we are not yet to that stage of technological development where we can interface with computers by any but the most direct means - pushing buttons - I have racked my brain to figure out what sets these unfortunates apart. It's not like they ooze a substance that jams the machinery! My theory is that it has to do with their magnetic field.
Each living being generates a low-level magnetic field. And I have not enough science to know if it is in any way related to the body's ability to build up an electrostatic charge of as much as 20,000 volts. We've all had days where every bit of metal we touch shocks us; well, it makes sense that we could be releasing energy through keyboards into computers, in such immeasurably small amounts that no significant damage is done, but it's enough to make things (in my favorite scientific term,) wonky.
We're still in the first generation of widespread computer technology, and 100 years from now, it will probably be possible to measure such tendencies, as organic bodies continue to increase their interface with the inorganic.
But I want it established that I thought of it FIRST. :)
