  and destroying something likely not replaceable. A person could be put
  in jail if the lord of the land was pissed off enough.)

- put a plate of milk outside for the faeries so they don't suck your cows dry
- Never place a mirror across from your front door
- step on a crack, break your mother's back
- idle hands are the devil's playground
- cats should never be allowed near babies as they will suck the breath from the child and suffocate it

Superstitious Belief Has a little Scientific Basis,but most of it are not scientific.

Mali naman hinahanap ko with scientific base yan naman wala eh

No there is no link between superstitions and scientific basics. Let me tell you one superstition, where many people believe, if one black cat crosses your path while you are going out, is there any scientific link to it, no I don't think so.
