Two students are discussing whether hand sanitizers are unhealthy. Jane: Hand sanitizers make germs stronger! Viruses evolve to counteract ways to stop them. Overusing hand sanitizers helps germs resist antibiotics. Hand sanitizers are actually training germs to hurt us! Tom: There is no proof that hand sanitizers help germs become resistant. A hand sanitizer should never replace the act of washing your hands. It is for quick cleaning, like in hospitals, or when there are no sinks available.
