This is horrible, even if he regains consciousness he will not be the same man. I guess it is also a reminder that one must always respect animals not never drop your guard. I hope he recovers fully with all his marbles in the original basket.
Yes that is horrible. I had a teacher who got kicked by a horse and she loved horses. It just teaches us to always be on guard with our animals and to respect them. I hope that he gets better soon.
