* Fly: Horses are mammals and, unlike birds, they lack wings.
* Breathe underwater: Like most mammals, horses need air to breathe and will drown if submerged for too long.
* Speak human language: While they can communicate with each other and humans through various sounds and body language, they cannot speak our language.
* Read or write: Horses lack the cognitive ability for these complex tasks.
* Operate complex machinery: Their hooves are not designed for operating machinery, and their lack of opposable thumbs limits their ability to manipulate tools.
It's important to note that these limitations don't diminish a horse's incredible capabilities. Horses are powerful, intelligent, and sensitive animals that have been companions to humans for centuries.
