Is it normal to get injured on purpose while working to get sent home?

Not normal, it just means you're useless and lazy. I might even go so far as to say you have a mental illness. How can you think injury and pain is worth temporary rest?

You can only accidentally sever so many fingers, toes, and limbs before you run out of options.

When you're a quadruple amputee, your options are limited when it comes to finding a job you can shirk.

Totally normal if your job sucks ass lol

That's what Dan Bilzerian kinda did in training for marine corps

I would say this is normal, but I think the reason is a bit more deep-rooted: You gotta find yourself a job you like and reward yourself for doing well, so you can dig yourself out of your hole. You sound a bit like me when I am depressed, you need to pick yourself up and get productive, you'll be happier!

That work great. If you live with your parents and don't need to pay for shelter, heat, food, ect. Are you a women?
