    when your car is braking.

    Procreating would be another great purpose..

    It can sharpen your tongue. 

    to keep a biker on his seat


    to keep cars on the road 


    to help cars and bikes to brake 


    when sanding wood


    to start a match


    to stop slipping on any suffices 


    to help us pick things up or grip things


    to stop our shoes from sliping


    unable to write with out friction


    to help us to stop when running


     


     

    What first came to mind was on a vacuum cleaner belt....

    We use it and depend on it "Every day in every way"
