Forget your birth certificate – there is only one definitive way how to find out how old you are.
And that’s by playing this mini game, of course.
Car parking website Just Park (yup, that’s a thing), surveyed 2,000 people on their emergency stopping time and used the results to create this game.
Simply click or press a key when the big stop sign comes up and they’ll use your reaction time to tell you how old you are.
It’s basically science.
