Who was the first to say "Life is like a roller coaster"

I doubt that it is possible to know the source of this common phrase.
Like many adages, it has been passed along in various forms for
generations.

In the 1950s my Great-Aunt Mary used to say "Life is like a roller
coaster: It's a bit slow to start. It gets fast and blurry in the
middle. And you're sick when it ends."

Thanks for the response.  I like your Great Aunt Mary's statement....smart lady!

The quote is attributed in a few places to "Andrew A. Hagen".

But I have found no references to this alleged originator of the quote
in other contexts on the Web, or in online bookstores or national
library catalogs.  Thus, I suspect that the answer is not really
"Andrew A. Hagen".

I am informed that Arlen P. Glick said that immediately after failing
his final exams at Princeton, in 1921.  Or so his widow told me.  But,
of course, it's impossible to know if he was merely quoting someone
else.  How does one ever know who actually said something first?  All
we can ever find is the first published utterance.  Many quotes are
attributed to loads of people.  Quotes about New England weather have
been attributed to Mark Twain, Mary Kay, FDR, etc.  As an author
myself, I've found whole stories I've written, copyrighted and
published nationally, posted on the Internet as "anonymous" or even
with the local website owner listed as the "author".  Be careful when
you are told a provenance and always look further.

Andrew A. Hagen is a person who regularly rates books on the
Amazon.com site.  In his ratings, called "Listmania" by Amazon.com, he
often uses lots of cliches and shopworn phrases.  He has listed
himself as a "recent law school graduate" so doing a search on the
'net may have picked up one of his uses of someone else's phrases.
