From Alec Cawley
In suggesting that we should all have bar codes in our foreheads, your
correspondent Brian Moss is millions of years too late
(22 January, p 50).
Nature has already marked us with unique patterns of lines, on our fingertips
and retinas amongst other places. Those on our fingers mark every manual
transaction we make, while those in our retinas will, if current predictions
come true, soon be read automatically without our knowledge. Nature has prepared
the way for Big Brother.
