Hand washing! Gee, I think it was in the news when Florence Nightingale was teaching 100+ years ago. Probably the single most effective means of disease prevention.

Until They Squeak

Oh, doctor
All I ask, is please,
Go wash your hands
Each time you sneeze,
And every time
You spit or cough,
Make sure you wash
The germs all off.

Because studies show
That very often,
Doctors pick
Their patients coffin,
So listen up
In layman's speak,
Please wash your hands
Until they squeak.
