Sara Loughnane: We think we’ve all got pretty amazing bodies actually and we are going to tell you just a few things that all of your bodies can do, and do do all the time, that we think is pretty cool.
Cathy Buntting: Well, the first thing - did you know that the average person will cry up to 7 litres of tears of in a year. That’s seven bottles of tears.
Sara: Did you know that you have got about 2 million bacteria on your face right now.
Barbara Ryan: And did you know that bad breath is caused by food odours and mouth rot – that’s millions and trillions of little critters that live in your mouth, they swim, and they reproduce, and they poo, and they die in your mouth.
Cathy Buntting: And that’s just normal.
Sara Loughnane: And your body totally deals with that.
Cathy Buntting: Another amazing thing is, who knows how many hairs they lose off their head per day? Who will take a guess?
Student: 70.
Sara Loughnane: Pretty close.
Student: 100.
Sara Loughnane: It’s 80. Every day.
Cathy Buntting: And what I want to know is, who actually counts those hairs? Like, how do they work that out?
Barbara Ryan: And sweat is a natural air conditioning. So it oozes out of your skin to cool you down. And it’s not your sweat that smells bad, it’s the bacteria that eats the sweat.
