Keeping your mind sharp and your brain healthy can be equally as important as staying fit and active.
And one way to test your brain's abilities is by tackling a puzzle or two. Brain teasers can help sharpen your focus as well as polishing up your problem solving skills, challenging you to think a little differently. Illusions allow you to improve on your ability to perceive and interpret visual information as you work out what on earth in going on.
So why not take on this brainteaser to put your mind to the test? The picture challenges you to figure out which of the two women is the boy's real mum. If you can do in under seven seconds, you might be considered a genius, reports the Mirror.
The image shows two women facing each other while a young boy sits and plays with his toys on the ground between them.
But can you figure out which lady is his mum?
At first glance it is tricky to spot any differences between the two women, leaving many scratching their heads.
However, if you look a little closer you may notice a couple of details that make it 'obvious' who the real mums is.
Got it? If you are still working things out take this as your spoiler warning!

The answer is the lady on the left.
There are a few little clues in the image, for example the matching. hair colour, the fact the little one is facing the woman in green while playing with his toys - which indicates he feels more comfortable with her.
The woman on the left is also leaning forward in her chair while the lady on the right is relaxed and upright, with the lean reflecting a mother's natural instinct to protect her child.
