Hereâ€™s an ad thatâ€™s sure to make you take notice. At first glance it appears there is a woman lying unconscious, face down at the bottom of the stairs. As you rush to help though, you realize that itâ€™s just a decal. The ad states â€œKnow what to doâ€ and is a campaign by the Red Cross to shock people into understanding the importance of learning CPR and first aid. Realism is definitely one way to get your point across.
