[Chromosomes] codon usage bias in humans ?

I have been studying biology in the 70s and been out of the loop for a
I came across this on the web and try to figure if it makes any
scientific sense - I know all possible codons are assigned to amino
acids (or stop/start) but is there a bias in humans as to not use any
of them or many as proposed here:
does the following text make any sense?
He was taken to UCLA to see what was going on and those tests showed
that he didn't have normal human DNA. In the human DNA we have 4
nucleic acids that combine in sets of 3 producing 64 different
patterns that are called codons. Human DNA all over the world always
has 20 of these codons turned on and the rest of them are turned off,
except for 3 which are the stop and start codes, much like a computer.
Science always assumed that the ones that were turned off were old
programs from our past. I've always seen them like application
programs in a computer. Anyway...this boy had 24 codons turned on - 4
more than any other human being. Then they tested this kid to see how
strong his immune system was.
