When I was a kid there were certain houses that when we went to visit them, we had to remove out shoes, the second we walked in the door. I always thought as a kid it was a weird and stupid idea, almost to the point where I dreaded visiting those people.
But it turns out that those people were exactly right and had the proper idea. You see when we walk anywhere outside, be it the park, the public toilets, or even just the local shopping centre we are transferring germs from the floor to our shoes. Now if you then walk into your house and don’t remove your shoes, that same exchange happens between your shoes and your soft furnishings. So that pidgeon mess you walked in without realising it is now being ground into your carpet or sofa. Makes you think, doesn’t it. Watch the video for more information.
