"Are you human" words while encountering certain pages

Are you human, are you human ... God, these words I've seen like a million of times and I can't get rid of them. Either while registering, or applying or simply getting ready to watch my Chinese and other dramas. It's always those words.

Ok, we don't have a choice so we click "yes". Naively, it's not over. You have pictures of cars/vehicles, bicycles, even hills to mark. Hills, you may ask? Exactly. In these tiny pictures, I need to find even hills. I must say, traffic lights and bicycles confuse me cause traffic lights have piers and bicycles have people therefore, what exactly should I mark? Same with stairs. Does handrail count?

When I finally manage to mark them, there is another round although it's correct and, another one. Frankly, my fingers feel tired even without this trouble. Yes, I could quote Taylor Swift on this:"I knew you were trouble when you walked in".

In the end, aren't humans those who make mistakes and are sometimes proud of them?
According to Google and others, I guess, we don't.

Just, let me tell you. Even if we succeed instantly marking these pictures, doesn't that make us, in fact, robots cause, a robot is always right? :)

Ah....
