This exciting series zooms in on the little things in life.
Peek through the microscope and take a look at the tiny things all around us: the lives of bacteria, viruses, fungi and parasites.
How bacteria are there on a human hand?
What viruses can be found on a mobile phone? And what is living in your eyelashes?

Not got the faint-hearted, this series looks at the little critters we all live with, and can't live without.
