Random Thought
I started off working in the food industry. You are always told to use hot water when washing your hands. Now this has never made sense to me.
At the temperature needed to kill off bacteria wouldn't I burn my hands?
Also what's the soap for then?
We don't brush are teeth with hot or warm water.
Please someone tell me if I am missing something here. I would really like to understand this.
