This quiz is a bit of fun! Will you laugh it off and answer all our questions or will the joke be on you?

#1. What does this emoji 😆 mean to most people?

The ‘smiling face with open mouth and tightly closed eyes’ emoji is the world’s most confusing. In a US study, scientists found that half of people thought it was a positive emoji, and half thought it was negative!

#2. Which of the following is not a stress hormone that is reduced by laughter?

Polystyrene is not a hormone, it is a plastic.

#3. Some cultures see a smiling face when they look at the Moon. What are the dark patches you can see actually?

The dark plains on the surface of the Moon have the names of lakes and seas, but they are caused by asteroid impacts.

#4. True or false? It takes more muscles to frown than smile.

False! This is an urban myth; researchers have found that the number of muscles used depends on the extent of your smile or frown.

#5. What kind of groups do hyenas typically form?

Hyenas live in structured groups, called clans, of up to 80 individuals led by one powerful alpha female.
