Some things that we assume are clean, are in reality very dirty and disgusting. For example, our mobile phones. Researchers have found out that there are more bacterias found on your phone than in a toilet. Experts have said that the reason for this is because our phones are often being passed around, which means that the germs are being passed around too. Since the bacteria on our phone are never cleaned, this means that diseases are being accumulated and keep building up. Professor Gerba also suggested that we should wipe our phones with antibacterial substances occasionally to prevent the building up of diseases.
