Tie Your Hair Back!
Get it out of the way!
Why tie your hair back???
Tying your hair back eliminates any chances of an accident with your hair with what your doing. Putting it back in a pony tail can help you from it also getting in your line of view so you can see properly.
Keep it out of your eyes and away from the device your working on.
It would be a shame if it got caught in a fan or a moving part that may catch your hair. You would have to cut it off and probably ruin your device your working on.
