Why do we need friction in our world?

Biology

Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.

Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. While walking, you're pushing your foot back as you try to step forward. Friction holds your shoe to the ground so you can walk around.

"<span>water-soluble vitamins can build to toxic levels ..." is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.</span>
