Do you believe in superstition?

there are many superstitions of this world. as i was just thinking about it, i noticed my left ear is red and feels extremely warm. apparently that is a sign that someone is talking bad about me.

i did some research to see what else could be the problem and found it's also caused by blood flow rushing to the ears. seems normal enough. it's annoying though,and i have resorted to applying something cold to cool down the area, although when i take off pressure, my ear gets warm really quickly again.

another superstition is that if you open an umbrella in your house it is bad luck.

the main question i have, is do you believe in superstitions?
