What happens when a fly lands on you?

Flies can't digest solid materials, so when they land on you, "they are 'sopping' up the moisture from the skin," Duncan says. "This process is done with their sponging mouthparts. That is why, if you watch, they are constantly dapping the skin to gather as much moisture as possible."

Can flies see into the future?

While flies don't have the ability to time travel or see things that haven't happened yet, they do have the ability to see into the relative future. Since a fly point of view and subsequent communication processes are so fast, they will find out about something 4-5 times faster than the average human.

Do flies see us as slow?

The answer is that, compared with you and me, flies essentially see the world in slow motion. To illustrate this, have a look at a clock with a ticking hand. As a human, you see the clock ticking at a particular speed. But for a turtle it would appear to be ticking at twice that speed.
