Fat bacteria?

The notion of obesity as an infectious disease
is unconventional, Atkinson said, but he added,
"Fifteen years ago if you said ulcers were due to
bacteria, people would have said you were nuts,"
and yet that's now known to be the case.

I like the "unconventional" part of that.

Then again, we're exceedingly good a laying off
our problems on some 'outside factor', aren't we.

I can hear the Fat Ones say, "I knew it wasn't
my fault."

What might be the truth?

All the report.
