The thing is also that:

Biting your nails can lead to significant damage to your teeth, including chipping, cracking, and shifting out of alignment. Additionally, it increases the risk of gum disease due to the transfer of bacteria from your nails to your mouth.

It's not worth it. Life is not about gum disease and damaged teeth.

It's also still not good to rip your nails as what happens with biting. It causes damage to your nails even if you don't bite all the way down "to the meat".

And if you just search the internet for nail biting, there's SOOO many complications that can occur with nail biting, and so many bacteria you can ingest that can get you very sick.

Basically,

it's fucking nasty as fuck.
