With apologies to Annie Lennox, Walking on Broken Glass is not all that difficult.
I just made a YouTube video of me crushing broken glass, barefoot.
Broken glass is not all that dangerous. Yes, it is possible for it to cut you, but you really have to work on it.
Skin simply does not puncture easily (and that is true even for those who don’t regularly go barefoot). You can slice it though. As long as you are not sliding your feet along a glass-strewn surface, you are pretty safe. (And even then, suppose you get a cut of some sort—have you never gotten a cut on any other part of your body? Stick a bandage on it, and continue on, for pete’s sake!)
At Thanksgiving a few years back, my visiting brother-in-law broke a beer bottle in my garage. He was extremely concerned when I came to help clean it up. Then when I stomped on it, I thought he’d have a panic attack. Again, no big deal.
People are so wedded to their mythologies that they just cannot accept that their fears are not based on facts.
