This quote from the article is EXACTLY why I prefer hot horses :)
Researchers Develop Subjective Equine Personality Test | TheHorse.com: ""For example, a neurotic horse will be more prone to stress and will be more likely to spook, which may be difficult to work with. On the other hand, their sensitivity means that they are incredibly responsive and can thus appear 'in tune' with their handler. If you're a good, calm handler, you can get amazing results by putting this to good use.”"
