10 Shocking facts brought to you by Saif Ausaf
#1 50% of women contain a 4th color receptor in their eyes in addition to the normal 3, and can thus distinguish between more colors
As an example of how this works, where most of us may look at a rainbow and see seven colors, a lucky lady with that fourth receptor will actually be able to make out 10. An even smaller number of women end up with 5 color receptors!
#2 Humans are the only mammal that cannot swallow and breathe at the same time
You just tried to do it, didn't you? The reason for this is that humans' voice boxes are unusually low in their throats compared to other animals. In turn, this allows our voices to resonate much more, which allows for us to produce such a wide variety of sounds!
#3 It can take 4-15 months for your blood vessels to fully recover from a sunburn
Don't go outside without sunscreen! You've probably heard people tell you this all your life, but this is just another reason you should really listen to them. Your body might still be recovering from that bad burn you got last summer when next summer rolls around!
#4 Feet have more than 500,000 sweat glands and can produce more than a pint of sweat per day
Ever wondered why old socks smell so much worse than any of your other sweaty clothes? Just remember to scrub your feet extra well next time you take a shower, alright?
#5 Part of the reason you can't open your eyes when you sneeze is because sneezes regularly exceed 100 mph
It's like every time you sneeze, you're shooting an MLB-quality fastball out of your mouth! Also, this is where we make the customary request for you to PLEASE not try to open your eyes while sneezing.
#6 Heart attacks are most likely to happen on a Monday
This fact brought to you by a 10-year study in Scotland, finding that 20% of all heart attacks happen on Mondays. It could be due to drinking, or the unhappiness of going back to work, or the stress of going back to work. In any case, always make sure your lifestyle is healthy for you!
#7 Every pound of fat you gain causes your body to make 7 new miles of blood vessels
If you've ever wondered why obesity and heart disease are connected, now you know at least one of the reasons. Just another thing to motivate all of us to eat healthy!
#8 The average person in America/Europe eats 50 tons of food and drinks 11,000 gallons of liquid during their lives
To give you a clue, this essentially means that humans eat the equivalent of one humpback whale worth of food during the course of their lives. Which does not mean you should go hunting whales in the hopes of having a lifetime supply of food. Pretty sure the whale will go bad before too long.
#9 The acid in your stomach is strong enough to dissolve razor blades
Think of how tough the lining of your stomach must be, then! Note: We do not encourage anyone reading this to try swallowing razor blades, and in fact would request that you avoid doing so.
