Yeah, I have seen the animal bleed out once, and it is hard to watch.
A small and young lamb is all tied up laying on the ground with the carotid severed. It is clearly in fear and tries very hard to get away. That struggle lasted for a long time until it eventually is exhausted and died.
I am not sure if this is how halal and kosher meat are produced though.
I never talked to my parent about this, but I imagine way better. My dad is one of the earlier master degree holder in China. He got his PhD much later; I believe around his 40s.
At my age, my dad is an entry level doctor and my mom an entry level nurse. They live in a room of 10 square meter assigned by the hospital they work in.
I am now a professor, a very busy job, but nevertheless stable. The pay is not bad (not as much as industry though) and the work is really fulfilling. The only unfortunate part is that I almost always need to work overtime. It is not uncommon for me to work from waking up to going to bed, if not working into midnight.
