Why do people 'crack' their knuckles?

[steve-h]

I do it because i feel like they need to be clicked, and no it isn't bad for your joints and doesn't give you arthritis. They are common myths

TRU DAT

It's more of a habbit now... however every other bone in my body 'cracks' without me trying.

 

[vincent1989]

Crack all of my knuckles, my elbows, all of my toes (the big ones continuously), my knees, back and neck, feels good man!

Habit, simple as really.

 

[Deleted User 234324]

Do it all the time, also crack my back and neck as well.

This. I tried to stop doing it awhile ago, but found myself doing it automatically when I was idle and wasn't thinking.

I can also do it with my knees if I bend them and sink down, that tends to freak people out!

Both my knees do it every time I sink down and kinda sqaut. Only does it once and then will be some hours before it does it again but it freaks people out as it is so loud and sounds like my legs breaking.

No idea why they do it but it won't cause arthritis or any other issues for them when they're older. The 'cracking' is simply air in the fluid that surrounds the joint being compressed and popping.

It causes absolutely no harm apart from the obvious annoyance to everybody else!

My colleague does it all the time... and it really annoys me.
It sounds horrible and I don't think he realises that he's doing it.

Isn't it bad for your bones?

They know their doing it, it's a bad habit that their use to.

It isn't particuarly bad for you're bones though, but I too use to think it was!

To annoy those who don't

Only time I crack my knuckles is when I punch someone's face.

I do it when I'm about to punch someone.


And by punch someone I mean sit down at my computer and get my uber micro on.

lol

Feels good brah.

 

[panyan]

Does not cause arthritis, or any of the other myths people think

+1

a lot of people think it is bad for your joints, but it was proved to be absolute nonsense

It used to be a habit of mine and I just couldn't help it. My fingers are now very thin and some are slightly bent due to cracking the end of my fingertips all the time. Really regret it.

 

[needforspeed]

I can crack my tail bone.

 

[Cosimo]

Just had a good crack.

 

[Witor]

Me siente muy bien hermano.

 

[MisChief]

Just had a good crack.

Thanks for the info...

My hip always click when I stand up from sitting, and my knees click when I bend down. Horrible

I knew this lad once, his name was Jacob and I thought that he was a bit crackers.

Cracking of your fingertips?

I crack my knuckles mainly out of habit. Sometimes they feel as though they "need" cracked though. My chest also cracks if I stretch it out.
