Thought never to return to post to this thread again (guess why), but...

"Because of the earlier flight, the Nashes' car service wasn't there to greet them, and the couple didn't have a cell phone. They waited with the Nirenbergs in terminal B, chatting to pass the time."

--from The final days of John Nash: the untold story of his 'dream week'

Apparently the Nashes may well still be alive if they had a cell phone.

On the other hand, it says something that they didn't use cell phone...



P.S. It reasonable to infer that the Nirenbergs also didn't carry a cell phone with them, either, for otherwise the Nashes could have used their cell phone to call car service. (noted: Nirenberg is 90, Nashes in their 80s "OldieInAmerica" )
