I have been consuming my own feces for years
Why would you eat your own poop?
I believe eating my own feces will make me smarter
I mean, be my guest and continue as you're not harming anyone. I do think it's bad for your health, especially since you've been consuming it long term.
If it's not bad for me then why should I stop?
It is definitely not good for you to be consuming your own feces. You should see if you can find something similar in taste to eat that isn't so hazardous to consume instead.
