Its a habit . They see there parents do it or there friends . And they follow
The average human has 10 fingers. For the sake of pedantry, a thumb is a specialised finger.
I'm guessing by clicking you mean the sort of popping action people do when they sort of push their knuckles. This is completely harmless in the long term and will not misshape you fingers, make your fingers shorter or give you arthritis. It's all just an urban myth. When you do click your fingers or pop your knuckles the sound isn't the bone cracking or hitting against another bone, it's simply a small bubble of trapped air which squeezes its way free through a small space. Kind of like poking a balloon with a pin. It creates a small hole and all the air tries to escape at one making a bang. That's all it is. Nothing damage, nothing to worry about. Unless you do it too hard and break something :P But that's not likely to happen.
I have been practicing for about 60 years. Still can't snap my fingers. I know the sound comes from the finger hitting the palm of the hand, I figured that out on my own as I studied other people snap their fingers.
thumbs are not fingers because fingers have three joints and thumbs have two
No, as far as people no atleast. For There is no proof or record of this condition. If there was, the person would most likely have been exposed to radiation since birth. IN which i doubt he or she wouldve lived.
when you crack your fingers, your fingers can't bend when you're older.
when you crack your fingers, your fingers can't bend when you're older.
No....
Now, if you are still young and growing, your fingers will stick grow even if you crack them.
yes no they can't you'll get really sore fingers if you do when you grow older
No it is not because you could eventually break your fingers it does become a habit try to challenge yourself to not crack your fingers for a whole day if you do that congratulate yourself by dong something special.Recent research is showing that people who do crack their knuckles may be more prone to arthritis in the future. This is a good reason not to do this.
it is not very annoying at all if you crack your own because you cant complain to someone, that of what you do and mostly the only person that would think it is annoying is the teacher in school :]
you become a pineapple :D
Don't do it. It's bad for your fingers.
No. Your knuckles crack because of gas bubbles formed in the joints under pressure.
yes people do have fingers
If you have not found out already,here is one way to crack them:ball one of your hands into a fist,cuff it with your other hand and loosen the fist,than push forward with the other hand.All this should be horizontal.Oh sorry,you said fingers not knuckles.
