Scumbag Brain

Probably because they see something they like so much that they get addicted to it. Like I'm addicted to the song, addict, HA.

Good question
And I can’t answer...

I think it's due to how the brain works. There's like this little switch thingy in the brain (not really, but you get what I mean) that turns on if you really like something. That's called addiction

Probably explains why I'm a pizza addict (sorry couldn't resist)

Dopamine
