Dr as in "Dr Nick"
Simply looking at it, it seems obvious that the carpels will be doing *more* work than with a regular mouse! Using a wristpad, a trackball, sitting correctly at your desk, adopting a dvorak or colmacs keyboard layout that reduce finger travel ; those are solutions to RSI (which in the main part is caused mainly by bad typing posture rather than mousing).
Then I saw... as recommended by a chiropractor. Bazinga confirmed.
That lovely bunch of ch*rlatans who aren't answerable to, or registered with the general medical council, aren't usually permitted to prescribe drugs, who on occasion don't "believe" in vaccination, and don't bother with a little thing like double-blind case studies to support their claims... but somehow get away with calling themselves "Doctors" and manipulating the spines of children (and relentlessly pursuing critics with legal action).
I've heard a first hand account of a person hobbling into A&E with a broken bone in her foot. Her chiropractor had put the pain down to a spinal alignment problem and for the previous month had been giving her twice weekly spinal manipulations at fifty quid a pop. My own aunt was fleeced by these wiseguys who had no problem doing some joint cracking on the (recently broken) arthritic wrists of an 85 year old.
If their previous is anything to go by, they can shove that mouse up their 10th charkra and call it "medical science".
