I do this weird thing where I bite my own feet.
Is biting your feet something you might consider stopping?
I will not do so, I would rather die.
What you do with your body is your own business as long as you aren't doing any long term damage to yourself. Talk to someone about this to see if you have a fixation or obsession of some sort.
I will continue to bite my feet no matter what others say.
It's not really a sanitary thing to do. Aren't you concerned you might get a foot fungus in your mouth?
