How you can possibly type with the thumb on a cell phone is beyond me, or I just have large hands. The GameBoy is a completely different matter.

Or you could be one of those "less used to mobile phones."

I don't know. This sounds bogus to me, kind of like the giraffes who got longer necks because they were always stretching to reach the higher leaves on trees.

The use of gadgets such as mobile phones and GameBoys has caused a physical mutation in young people's hands, according to a British Sunday newspaper.

I doubt this is a true physical mutation. I'm guessing that if all the game boys disappeared, the offspring off these kids would not show this manifestation.

Anyone can see that years of repeated physical motion will rewire the brain -- otherwise there would be no musicians. But that is not a mutation.

In her research, Plant noticed that while those less used to mobile phones used one or several fingers to access the keypad, younger people used both thumbs ambidextrously, barely looking at the keys as they made rapid entries.

And that's how we use graphing calculators...
