Douglas Adams: Parrots the Universe and Everything

A monolith as a headstone?
And dying in 2001!?

I have not read any of Douglas Adams novels, but I saw some of Hitch-hikers Guide to the Galaxy. 

I mainly like having a chuckle at quotes that are attributed to him.

I knew he died, but I didn't know when. 
I was surprised that he died on May 11th, 2001, at the age of 49. 
I didn't realize he was that young.
May 11th is my wife's birthday, and her father died from a heart-attack as well.
I thought it was odd that I found this video clip of a talk he gave called, Parrots the Universe and Everything.

Which made me think of what I termed at the time  
"The Parrot Sync"
John and the Wild Parrots
although I was talking about lorikeets I soon found out.

I like how on the You Tube site I got this clip from 
it said there were 4,242 likes, 23 dislikes.
Which combines  my father's cab number 424 with Douglas Adams' answer to the meaning of life in his Hitch-Hiker's Guide to the Galaxy novel ... 42.
Or 42/42. 
Also he was born on the 11 March 1952 and passed on the 11 May 2001.  
11:11???
