Roll Safe Think About It

99.9*99.9*... This sequence will never reach 100 and you'll be left with the Chuck Norris if the germs. Good luck with that.

but you will only kill 99.9% of the 0.1 %

it doesn't work like that my friend. the 0.1 percent are a hardy bunch.

Then you won’t kill all that is left, then you’ll use it again and not kill all that is left forever.
