Looping through repeater fields with a foreach loop

Hi I am trying to loop through a set of repeater fields that I have set up and populated within my post.

I am trying to implement this code on my single.php page but for some reason I am getting no output.

Anyone have any ideas?

<?php
		$questions_and_answers = get_post_meta($post->ID, 'question-answer', false);
		foreach ($questions_and_answers as $single_questions_and_answer) {
			echo $single_questions_and_answer . '<br />';
		}
	?>

question-answer is my field slug.
