Why You Should Always Wear Your Helmet.

reblog to save a life

Whenever I see a biker or cyclist without a helmet I can’t help but smh

There’s a lot of by bicyclists around our city that don’t wear helmets and it makes me cringe each time I see them.

The average thickness for a human skull is between 6.5mm and 7.1mm.

Yes you read that correctly. MILLIMETERS.

That’s not enough millimeters to keep you alive if you throw in some speed and hard surfaces.

Please wear your helmet.
