Indian beliefs and their roots - Belief 1

Indians have weird beliefs. Sort of superstitions. Here I intend to come up with the true reason (or similar one) that probably gave rise to such beliefs. Here we go...
Belief: Dont clean your ears at night

Someday I was feeling so itchy in my ears that got a earbud and started cleaning it. My mom was for a minute frozen to death. She said "dont clean your ears at night". Promptly I asked her why? She said thats the rule, dont ask why. I argued with her for a while not to believe in all these things, but in vain. Then I started thinking, there must be a reason for introducing such a rule. Indian civilization has been around for a long time and were far more advanced than other parts of the world. There must be a reason to have such a saying. So I thought for a while. Here is what I came up with.

• The time when these rules were written, they didnt have electricity or light bulbs; they had lamps at the most
• they didnt have ear buds from Johnson & Johnson. they prepared their own from a stick and cotton hopefully, but mostly primitive.
• groping in dark is never good, especially if the path is so constricted as your ear canal
• if anything goes wrong, you would directly puncture your ear

and hence dont do anything that can harm yourself in dark. This must be the reason (or in similar lines) for them to have introduced such a rule.
I got back with my mom to discuss this. Thankfully she was open to discussion on such a topic and agreed that something like that must be the true reason. But most moms in India would just brand you as a spoiled child if you argue with them about the blind beliefs.
I intend to write more about such superstitious beliefs. If you have a question, write it in the comments and we can try to come up with the reasoning.
