We all have ups and downs in life, peaks and valleys, and no one is immune. But it is all in how you deal with them — and I think that we have CHOICES.
For me, I try to learn from the unexpected things that happen - and make them work for me.
The swine flu spreads dramatically, everybody should take good care! Buying some disinfectant liquid and carrying it wherever you go.

HOW SWINE FLU OUTBREAK EMERGED
Flu viruses mutate over time causing small changes to proteins on their
surface called antigens. If the immune system has met a particular
strain of the virus before, it is likely to have some immunity; but if
the antigens are new to the immune system, it will be weakened.

The influenza A virus can mutate in two different ways; antigenic drift,
in which existing antigens are subtly altered, and antigenic shift, in
which two or more strains combine. Antigenic drift causes slight flu
mutations year on year, from which humans have partial, but not
complete, immunity. By contrast, the new strain of H1N1 appears to have
originated via antigenic shift in Mexican pigs

The name "swine flu" is a slight misnomer as it is believed pigs acted
as a mixing pot for several flu strains, containing genetic material
from pigs, birds and humans. Most humans have never been exposed to
some of the antigens involved in the new strain of flu, giving it the
potential to cause a pandemic.

The new virus has made the jump from pigs to humans and has
demonstrated it can also pass from human to human. This is why it is
demanding so much attention from health authorities. The virus passes
from human to human like other types of flu, either through coughing,
sneezing, or by touching infected surfaces, although little is known
about how the virus acts on humans.
