I heard all but the last one, so I can't figure out why my hearing is so bad in real life.
Maybe other people really don't talk clearly anymore
I wondered about all the marble-mouths I heard in daily transactions with the rest of the world.
But it was so universal that I finally decided it was me, not the people out there.
About 10 years ago I started to unconsciously and half-assedly lip read, but didn't realize it until one day I had to ask someone to turn around so I could hear him. It then dawned on me that I was actually lip-reading for much of my conversational information.
