BlackBerry users, for instance, use their thumbs to feverishly scroll through e-mails. They flex, stretch and move the digit side to side. The thumb isn't cut out for such dexterity work, says Dr. Andrew Sherman, an assistant professor of rehabilitation medicine at the University of Miami. The keys are smaller than on a computer keyboard so you press harder.

I have little sympathy for these people as I have seen people addicted to them. They whip out their PDA/MP3 player/cellphone/IM device and start tap tap tapping at the screen with a stic, furiously manipulating the scroll wheel, and franticly pecking away at the microscopic buttons. Its funny seeing them move their elbows up and down as they put more force on the hand currently 'pecking'.

Whole companies needlessly depend on the hive mind mentality of being in the know. As a result, people oftentimes have information overload or are bombarded with superflous emails or texts that nickel away at their workday.

Besides, these people just need to exercise their digits more. I can remember being ten and beating the living crap out of my thumbs on my Game Boy. And I was proud of my gamer thumbs, they withstood much punishment. I imagine if I had been a little more fit I could have balanced myself on my thumbs.
