I know it's kind of weird...but I like to take cold showers :)
That is interesting, did you know that the original showers were common natural formations?
I didn't know that, I bet it was cold as well. Once you get used to them, they are actually quite nice for waking you up.
If you think so. Were you aware of early signs of Egyptians having shower rooms where servants could bath them indoors?
I did not know that, but that's pretty cool. Do you know what material Egyptians used?

Response: Well, the material they used was ceramic.
