OT-- Exercise stability balls report

This is very off topic, but I wanted to bring it up today. I watched a report on Inside Edition last night and it brought up the serious dangers of those exercise stability balls. You know, the big oversized rubber balls that you can do sit ups, push ups, ect on? Anyway, most balls are NOT puncture resistant and if they pop while you're sitting on it, they blow up like a balloon. A man was using his ball while lifting weights and it popped. He broke both arms and may never fully recover. So, if you have one that isn't puncture resistant and it's made of thin rubber you may want to toss it. Companies now are making puncture resistant balls and if you poke it with a pencil, say, it will slowly leak air and not explode.

I have a non-puncture resistant ball that I've had for 5 years and I use it all of the time. I deflated it last night and tossed it. I never thought about it popping-and I should have since I have titanium rods in my spine.

Anyone else heard about this?
