Is breaking a mirror a sign of bad luck to come?

i am not really superstitious but my elders often tell me that there's nothing wrong in believing them and that we don't really have to live by the superstitious beliefs that we are taught. rather, these should be used to help us exercise extra care.

I am superstitious. I am a south Indian . As you know India is famous for superstitions. I generally dont believe at the first instance , but situation is what makes me believe , I have experienced it live. You may call it mind set , but I feel at some places this turns out true ...and so I have no other go but believe. I have heard about this one , But I have neither experienced nor watch its effects on other. So I am not pretty sure. This may have some science behind it , but still it yet to be proved. You may call me wired. But I feel in some aspects , its true.....

It is a supertitious belief, made by the elders of olden days to keep their nearest and dearest ones away from getting poked by the broken glass pieces.

for me, I'm sometimes superstitious because I seldom break mirrors so it would be a wonder if I break one hehehe
