I wonder how many of these 20 year olds would actually pass a vetting.
Don't know the studies that you are referring to, not going to pretend I do, I am basing my opinions on experience not something I read on the internet. This is what I mean by physical maturity; if he is too small to handle my weight I am not going to ride him. If he seems to having problems balancing is not ready for what I am asking he gets turned out. Again it's up to the individual. If I start two year olds it doesn't mean I am riding the piss out of them.
Just curious rbarlo, in your OP you stated that starting two year olds is not a common practice in the UK yet you are tired of seeing horses broken down from being started at too young of an age. Are you seeing these horses first hand or you reading about them? Where are you seeing these horses that are broken down?
