windhoek, I read your comment above with much sympathy coated with a layer of understanding, and to a large extent I agree with you, not withguarding some caveats.
Having had the same experience as you re bicycle accidents 6 months ago, I'll say honestly when I was lying in the street, passing out occasionally from the pain, the thoughtof not having painkillers never crossed my concussed head. Neither did the extended time in hospital, and, to be honest, I have no idea what they pumped into me. The only positive, and this had nothing to do with animal testing, the moment I was in rehab I stopped taking the paracetomol they gave me every mealtime, but that had more to do with my general attitude towards any drugs, which is that, unless it is a leafy green plant, I avoid.
Second caveat is that, a couple of decades ago we had a property of roughly 150 acres. This we let out to the local farmer for his sheep, which was a stipulation of my then girlfriend as she was against the needless slaughter of animals so sheep for wool seemed a better solution than cutting the fields with a mower many times a year. Nevertheless, come late winter and lambing, I would not want to think what happened to our flock's progeny. She did what she could, I was more concerned with debt, to be truthful.
We did, however, have hens. This isn't a defence, but the hens lived happy lives until either a fox got them or they died of old age. The guinea fowl never even had the egg cruelty, they nested in the trees because, basically, they refused to be ushered inside at night. Their progeny may still be doing so, as far as I know.
The difficult part is that I have killed animals, having made the decision to do so. One example was a cat, caught in a trap previous owners had laid for foxes. No question of getting close to it, this was a wild cat, and in agony. It was in a bush where it had gone to die, I assumed, and my friend's trying to cover it with a blanket only resulted in a quick trip to hospital for her. The animal was in agony. I made a hard decision and killed it. Similarly even here in France I've had to do the same, albeit with fledglings fallen from their nest or having been turfed out therefrom by their parents. The locals shrug their shoulders and leave them to die, mostly because pigeons are a pest.
What I'm saying in a rambling fashion is that yes, I'm 90%vegan, and for the cruelty to animals reason, but there are circumstances when we must take decisions that affect animals whether we like it or not. My examples are tiny, true, but while I eat eggs as little as possible now, for example, were I to have another smallholding I would probably have chickens again. Animal testing I abhor, and is another issue, in the sense that we are animals and I would support testing on our species. The other thing is that, if I can get to Australia, I will, even if it means having the vaccine. I'll try to get an exemption, though conscience is seldom taken as a good enough reason.
P.S. Euan has a good point.
