According to researchers, whether you see the old or the young person in that image (or in this one) says a lot about you.
If you saw the young woman first, it indicates you are more optimistic, happy and a bit impulsive.
If you initially saw the old man in the first picture (or the old woman in this picture ”” look again if you can't see it), it indicates you are more experienced and tend to think critically and see things from all angles.
Take a look at these other optical illusions and what your first impression of them says about you.
You've likely seen this classic illusion before. If you first see silhouettes of faces, you're likely looking at this picture up close. That indicates you like to jump right in when confronted with a problem and figure things out as you go.
If you first see a candlestick, you're probably looking at this image more from afar. That indicates you like to take a step back and see the big picture, gathering info and assessing the situation before approaching it armed with as much knowledge as possible.
Depending on whether you saw the duck or the bunny first, this could indicate a preference for your right or left brain. Or, more realistically, it could indicate what hunting season you believe it is.
If your brain can handle it, take a gander at even more insane optical illusions here.
While trippy, all these images illustrate the point that there are multiple perspectives to take into account before reaching a conclusion. This is important to always keep in mind before drawing a hard-line stance on anything. Try to keep an open mind and see what else you might find by looking at everything from different angles.
Also, if you're wondering about this image, if you first see a frog, it means you like frogs. If you first see a horse, it means you like horses.
