It seems to have a lot of benefits for our daily lives, but the fact that it’s a never-ending source of shared knowledge may be what makes it the best invention of the last few hundred years.

If you know where to look, there is no subject you can’t read up on and no answer you can’t find. We can solve mysteries that would have been impossible to solve for decades with just a few clicks of the mouse or keystrokes on the keyboard.

In the past few years, many old myths have been busted online. At the same time, life hacks and helpful hints have become common knowledge, when only a few people knew them.

For example, have you ever thought about why your underwear looks like it has a bleach spot on it? If you have, you’re not the only one. Women looking for answers have asked the same question online.

As well as answers they found. It turns out that those spots of color have nothing to do with your machine, as some people thought.

Different news sources say that these “bleach” spots are actually caused by the vagina’s natural pH levels.
