One of my first jobs was in a nursing home, and lemme tell you it's a pretty shit job. Not because of the specific working conditions, or because it's not fulfilling in many ways, but because you have to deal with a lot of gross filthy stuff and a significant fraction of your patients have dementia and are terrified, violent, or both. Being a vet tech is no picnic either but on balance I'd rather deal with animals than people.

I would say they are definitely in the same range that any difference is negligible.

Working in either shatters the soul in record breaking speed. The terrible things you have to witness. Humanity at its rawest and at times lowest. Both groups, no matter how many times you have to deal with the certain situations they do, you never get used to it (which is kind of important, as soon as you do get used to it, you've lost what makes you such a good nurse/vet - empathy).

Stupid you're getting downvoted. Veterinarians have some of the highest suicide rates. They go into the field wanting to help animals but instead end up dealing with the worst in human owners.

It definitely is, source - my sister managed an elderly care facility during the pandemic

My wife worked in aged care. There are plenty of nasty or racist old people in aged care that make their job awful

And what makes you think that?
