Here’s
one for the germaphobes. When you flush your business down the toilet,
it’s not a good idea to watch it swirl into oblivion. Researchers say
that if you neglect to close the lid before you flush, you’re unleashing
countless particles of waste into the air. British Professor Mark
Wilcox says toilet flushes can unleash a cloud of nastiness that can
hover in the air and settle on surfaces, possibly spreading sickness. An
experiment found that a toilet flush sent infectious particles 10
inches into the air, and traces were still found 90 minutes later.
Closing the seat still allowed the particles to escape when flushed, but
greatly reduced the revolting cloud left hovering over the toilet.
