Bicycles, roller skates and skateboards are dangerous. I still have scars on my knees from my childhood run-ins with various wheeled devices. Admittedly, I was a foolish kid, but I’m glad I didn’t spend my childhood trapped indoors to protect me from every bump and bruise.

The first step is to turn off the tracking software.4..
