I bet gum chewing can turn into a problem for some people.
Like maybe there are people who lose control when handed a pack of gum.
Rather than chew just one piece, they chew all the pieces so their mouth is overfilled with gum.
Then they make important phone calls to people.
But the person on the other end of the phone is like,
"What? I don't understand what you're saying.
Call me back when you have less gum in your mouth."
That would be a huge problem if you did that.
I wouldn't suggest doing that.
I wonder if 20/20 ever ran a story on gum chewing problems like that.
I'm sure they did.
Or, maybe they didn't get to it yet.
