So… Does cracking your knuckles affect your health in any way?

I know that my mom got me out of the habit of doing it at the age of 9 because she claimed that I would develop arthritis… That doesn’t actually happen, by the way. Totally a myth.

When you crack your knuckles, all the action takes place in the fluid that surrounds our joints, called synovial fluid. When you stretch your joints, you release gas in the fluid, which forms into little bubbles, and when your joints settle back into place, those bubbles burst and make a cracking sound. Want to crack the same knuckle twice? You’re gonna have to wait another 20 minutes for the gas to accumulate once more.

Sounds fairly harmless, right? But what does science say about this curious habit? Californian medical doctor, Donald Unger, decided to investigate, and dedicated 60 years of his life to the pursuit of the answer. Essentially, he spent 60 years cracking the knuckles on one hand, and 60 years not cracking the knuckles on the other, so he could compare the effects. Spoiler alert: None of his hands developed arthritis, and none of them were in more pain than the other.

Now lets get to the real danger with cracking your knuckles: driving everyone around you insane.

People have always had an appetite for science. But the way it’s been taught — where facts are poured into students heads and it’s called science — where’s the joy of discovery there? The science has been eviscerated of the curiosity, the stimulation of your curiosity that we take for granted as children.“

A scientist is someone who simply never grew up.

They’ve maintained their childlike wonder of the unknown. And we all have that within us.

I want to fucking punch every person who says “thank god” for Liberia being ebola free. Listen the fuck up!!! God didn’t cure them. Those health care workers did. And scientists who spend months upon months developing the medicine to help control it. Like how fucking blind are you. If God “cured” them then WHY didn’t he just stop the disease in the first place. And DO NOT try to tell me “he has had a plan, it’s part of his plan” bullshit. Shut the fuck up. And if this offends you sorry I’m not sorry. Find the unfollow button. If you want to believe in god. Cool. More power to you. But don’t give him credit for shit he didn’t do.

Elephant hug

Happy Birthday, Albert Einstein 

Born on 14 March 1879, died 18 April 1955, his 1915 General Theory of Relativity earned worldwide fame and a firm place in history.  His “services to theoretical physics”, in particular his discovery of the law of the photoelectric effect, won him  the 1921 Nobel Prize in Physics.  Dissatisfied with Newton’s classical mechanics and their limitations in explaining the natural world and specifically the newly discovered microscopic world suggested by the electromagnetic field, Einstein proposed a theory that addressed mechanics, electromagnetic fields and gravity.  The world relativity was first used in English as a noun in 1834 meaning simply the fact or condition of being relative, derived from the English adjective relative.  It first had roughly the sense that Einstein used in the work of English scientist James Clerk Maxwell in 1876.  The word relative was used in English in the 14th century to mean a relative pronoun-from the Late Latin relativus meaning having reference or relation, which came from Latin relatus, the past participle of referre meaning to refer.
