No. It's bad luck to be superstitious. :)
2. What extremes have you heard of someone going to in the name of superstition?
Can't think of any examples at the moment.
3. Believer or not, what's your favorite superstition?
Don't sweep the floor during the Chinese New Year or you'll sweep away the good luck. Hey, it's a way out of housework. :)
4. Do you believe in luck? If yes, do you have a lucky number/article of clothing/ritual?
No, but there are coincidences.
5. Do you believe in astrology? Why or why not?
No. Firstly, it's hard to believe that 1/365 of the population will all have the same fate. And secondly, the planets and stars are too far away to have any effect on you.
