Sharing is caring?

 One half of the mankind tries to teach what ever (or what little) they know to the universe and the other half tries with all its might to keep the folks ignorant.

It is easy to write such generalized far fetched observations. But I have observed that most of us have this deep desire to share our knowledge with others - if not whatsapp would have shut doors by now. 

Why do we share our knowledge - life hacks (genius life hacks like how to clean metal surfaces using tooth paste ;) ), health tips - about pain, about weight loss, about diabetes and so on? To impress people with our knowledge? To help people because they desperately need our help? To make us feel better by convincing ourselves that we are good people?

Or a hope that they will think she is not as dumb as we thought her to be. She knows things - like how to forward messages or how to copy urls. 

Or this is also another manifestation of our need to connect to people?

But we share - always - as can be seen with omnipresent share button.
