Hunter Thompson #1 quote according to whizzpast.com:
Contained in this quote is the same assumption which bothers me about the first poem in this thread Do Not Go Gentle Into That Good Night. As elegant as the poem is, it does not depict real life. Both the poem and Thompson's quote reflect a common but false, young man's fantasy about old age.
If "life" should be something other than "a journey to the grave with the intention of arriving safely in a pretty and well-preserved body", It will be literally impossible to "skid broadside, in a cloud of smoke", "and loudly proclaiming "Wow! What a Ride", when one is "thoroughly used up" and "totally worn out". In completely irrational doublethink, Thompson confers youthful vigor to old age. He literally cannot imagine what "used up" and "worn out" means, in advanced old age.
Similarly, Thomas' poem, Do Not Go Gentle Into That Good Night, inspired poetry though it might be, misses the most basic feature of advanced old age: feebleness and loss of intensity. He exhorts his father that "Old age should burn and rave at close of day"; "Rage, rage against the dying of the light". The young Thomas did his father's raging and raving for him, since his father was undoubtedly, long past doing it himself.
I will speculate about what might have been one of the reasons Hunter Thompson killed himself: Once he found out, through experience, what getting older was really all about, he couldn't accept it. One of the truest cliches out there is "You have to be tough to get old". Because, as the harsh physical and mental changes one experiences with age accumulate, one needs to accept, reassess and reorganize one's life to all the new, unpleasant realities. If you can't do that, you're in for a rocky ride.
