LPCHip: Oh...yes, I meant fortunately. Sorry for that mess.

Yes. When I was about six years old, I saw some documentary about cutting by water jet. I was frightened that water from water pipe in bathroom might cut my hands off, so I had not washed my hands for several weeks. When it started smell, my father took me to his work and showed me how does it work, so I could wash them without fear. Now I am really afraid of tropical insects.
