what will be will be so just let it be.
Actually I feel all these viruses serve a purpose in the great
circle of life.
Just imagine you have a fever, the body tempreature increases so
the heat kills off these viruses like common cold - it's all part
of self healing and renewal.
Just like viruses I feel they are there for self healing and
renewal, nobody knows where H5N1 or H1N1 why it suddenly appears
and disappears but imagine if the world had 10 billion people, 10
billion people eating and drinking and using up the worlds
resources, very soon there be no resources left to use.
So viruses are there to counteract as a balance and when the job is
done it disappears again.
