You just got lucky in that case and I would bet he did have health problems, you just didn't notice. And I have known rabbits live 14-15 years on a proper hay based diet. I have also heard of rabbits only live 6 months without hay And there WILL be hay in India, you just haven't looked hard enough.
Horses need hay as much as rabbits do, they must get it from somewhere seeing as you have horses in India (such as the Marwari).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
