His demeanor is still the same and isn't erratic or sluggish. He's still the same person I have always known, except for some maturing since high school, of course. There is nothing changing when it comes to his personality really.

Of course, he is a smoker but my grandfather was a smoker for much longer than my friend, and his teeth didn't look like my friend's. My grandfather had all of his teeth when he passed away. Of course, there are differences in quality of teeth but I was like "dang!" when I saw his teeth. His teeth are yellow and look like they have cavities. They're not black but brown and I was horrified.
