Germs Our bodies are pretty amazing; day after day they work hard digesting food, pumping blood and oxygen, sending signals frm our brains and our nerves, and much more. But there is a group of tiny invaders that can make our bodies sick - they`re called germs.

Dust build-up Dust build-up is predominantly made up of skin and contains mites. People can suffer from a variety of medical conditions due to prolonged exposure to dusty environments. Dust forms around the ventilation holes of computers, printers and photocopiers which not only causes heat build-up but also stores and spreads dust and germs around the workplace.
