Did you know?

While some of this might be untrue, I just multiplied the seemingly simple problem at the end, and sure enough, that's exactly correct! I also would definitely be inclined to believe the statement about the human heart. The body is an amazing thing! I also believe the statements about the butterfly and the cockroach to be true, and perhaps the crocodile, simply because when I think about it, I've never seen a photograph or video footage of a crocodile or an alligator sticking out their tongues! As for the elephant being the only animal on the face of the planet with the inability to jump; well, what about some marine animals? I mean, sure there are species of aquatic life that certainly do jump out of the water and back in, but what about the rest? It's hard to tell when you live on land, don't you think? Now, regarding a duck's quack being echoless, I do vaguely recall seeing this on an episode of Myth Busters on The Discovery Channel, but I can't remember what the outcome was! Oh well. I know a good site to debunk myths and rumors is Snopes.com. When something sounds like it may not be true, or if it sounds like it may be too good to be true, I always look it up on that site through a keyword search. It even gives the backstory on how different rumors and things like this are started!

Hi Alkurishy, very interesting information! Thanks for sharing with us! Now I know why there are still so many cockroaches around - they still can live for 9 days without their heads!!! I hate cockroaches!

I've read those beore. It's amazing what you can learn on line!

waayy! i love random facts, thanks for sharing

That's cool, thanks for sharing. I new about the heart one because of CSI. And the cockroach one is often heard a lot. The polar bear one is really interesting. And the duck having no echo, lol. I like looking up this stuff because it's just nice to know, you know?

i used to believe that a duck's quack cannot echo. i checked it out on the internet and it is a rumor. a duck's quack does echo. i've checked out other interesting facts that were emailed me and they also were false. anymore you have to check things out before you repeat them. someone is spreading untrue statements. they have nothing better to do than lie to well meaning people.

Those are some very interesting facts my friend and I believe they will definitely come in handy for example if an elephant is chasing me I can jump up somewhere high because the elephant can not jump up after me,and no I am not being sarcastic and I appreciate you taking them time to share these facts with us,and I look forward to anymore discussions that you post in the future.

these are great information to be kept in mind. now at least we know that left handed humans are inheritance of polar bears. thanks for the infos.

Good day.. Trivia is always a good thing to know. I hope people would post more about things like nature, science and history. I love to learn more of those things and widened my knowledge base.

Amazing! Yes, this information will definitely be useful to me :)

That's intersting! Good days,alkurishy!
