Okay, and there was a case of a woman dying at a hair salon due to having a stroke caused by the angle she was sitting at while at the backwash basin. The thing is, beauty parlour syndrome is rare, just like how successful ctbs from cutting are rare. No one is denying that there aren't cases of people who, whether intentionally or not, die from having their wrists cut but these cases of the minority. To succeed using this method you need to cut past the muscle layer, which can be incredibly painful. Along with that, you would also need to already be desensitized to gore (specifically in cases where it affects you, such as with more moderate to severe forms of SH), have a good understanding of anatomy, and have sharp enough tools. Most people are unable to meet all of these requirements, making this method incredibly unreliable for most and putting many at risk of permanently disabling themselves. The success rate for cutting is very low.
