HAVE you ever wondered why those little yellow Lego minifigures have holes in their heads?

Well, it's simpler than you probably thought.

The Danish toy manufacturer started putting the holes in the heads as a safety precaution.

Answering questions for blog Lego Godt, the company said:

"We added this hole on the top of the head just in case any kids got one of the heads stuck in their throat. That way they would be able to keep breathing."

In the same series of questions, Lego says it produces about 19 billion Lego pieces a year, and has made more than 400 billion bricks since 1958.
