Why do we have armpit hair?

You know how it is these days - you can afford to be inquisitive and know that all your questions will be answered - by Google of course!

    Recently, I wondered about the difference between POP and IMAP (both email access protocols) - and bingo "Google hai na". I was clear after 10 minutes of Googling

    Then again, I heard about GOP's opinion on joblessness (in US politics context) - and was surprised to know that GOP expanded into "Grand Old Party" (which is a nickname for Republican Party).

    Yet another time, I was researching on why we have the "pre-open" session on BSE and NSE stock exchanges since 2010 - and Google dished out a really nice article from indiabulls.com.

    Today, I got curious about why we have armpit hair. Some search results giving me reasons for armpit hair brought a smile. Here are some of the non-obvious ones:

• You know, when you put the hand under your arm, and close your arm down on it, and make that farting sound? The hair changes the quality of the farting sound, so when you have less hair, well, it just don't sound so good. But if you have a lot of hair, and it's nice and wet and sweaty, preferably as smelly as possible, why then, at summer camp, you can make the fake farts with the best of them. You haven't lived until you've been around ten guys all arm-farting at each other, especially when they get into a rhythm!
• It's there for babies to grab onto. Ouch!!
• One explanation for armpit hair is that it acts as a cushion to prevent skin to skin friction when our arms rub to our body. But this seems unlikely to be true. If it were, we should have a lot of hair on the bottoms of our feet.
• It's evolution. You used to be a monkey.
• I use mine to floss!
• To make you ask why  :)

(Ok, so there are two "real" answers for armpit hair - those I will leave to you to discover from Googling)

But really, the bottom line to this note is - Google is really that disruptive app that has completely redefined the scope of our access to information. May be, rather than teaching so many myriad subjects in school, they should teach just high level basics and a new subject called Googling.
