Lawnmower analogy was a bad one for sure. I'm more prone to falling down the stairs in my house as opposed to breaking a carboy. I've broken one carboy and fallen down the stairs 5 times in the last 11 years.
I broke my last carboy a few months ago. I had it for over 17 years, but wasn't brewing for part of that time. I paid $5 at a flea market for it, so I'm not too bummed about it. No injury sustained but as quick as it happened I can see how people do get injured. Knowing someone who had a nasty injury from one I know not to react to it slipping. Just let it go. So I just pulled my hands away. It only fell from about an inch above the floor.
I won't buy another. I have kids and they know to stay away from the brewing equipment, but things happen. I'm a bucket man. I had one I used for years. I only put beer in it and never scrubbed it. Spray hose and oxi-clean if that didn't work.
Lucky for me I just emptied the batch from carboy and was cleaning the yeast cake from it. I guess the positive thing was I didn't have to clean it.
