I actively eat my own skin and nails
Why do you eat them?
I like the taste!
Taste is subjective so I can't judge you for enjoying that.  However, it's disgusting to eat your own nails and skin, as well as pretty unhygienic.
You are wrong, I think it's a great way to start the day!
While you might enjoy it, it is not good for you. Eating your own nails means that you are putting saliva and germs on your fingers and then you are touching things which means you are transferring your germs to other people.
