Today the Spanish TV has given the following news: An English hospital
has discovered that the hands of the youths are having a mutation for
the constant movement of the thumb that presses the mobile telephone.

A doctor has said it in this TV, that it is similar to what happens
with the hands of the pianists who are gone conditioning the hand with
a flexibility and special adaptation with the help of practicing.

I personally don't see the likeness.  Better comparison should be with
the keyboards of computers.  What do you say?
