Interesting Encounter

Just as I was cleaning up after the dog during my morning walk with her, someone was entering the trail.  It was a man with scooter similar to this one:

His, however, had been "souped up."  There was a small electric battery sitting fore on the riding platform.  He had electrified the scooter.

He said to me:  "Have you ever seen anything like this?"

Me:  "No, I haven't.  That's very interesting."

He:  "I made it myself years ago."

Then I read a little hand-lettered sign (it was a small piece of whiteboard) which he had attached to the handle-bar uprights.  It said:  "I am 96 years old."

Me:  "You're 96 years old?"

He:  "No, 96 1/2 years old.  And I can do anything a teenager can."

Me:  {I'm wondering what to say to that.}

He:  "I can walk up stairs with both hand in my pockets and not stumble."

Me:  "That's great!  To what do you attribute you're being so healthy at your age?"

He:  "I keep active.  And  I was an early believer in taking vitamins and minerals."

Me:  "I see you're wearing a helmet, so you're safety conscious, too."

He:  "Yup."

Then he got on his scooter and silently glided away.
