Apparently also known as "
Man of Steel, Woman of Tissue Paper" to some noders. This
Larry Niven piece first appeared in Larry's book,
All the Myriad Ways in 1971.
"The purpose of this article is to point out some medical drawbacks to being a kryptonian among human beings, and to suggest possible solutions. The kryptonian humanoid must not be allowed to go the way of the pterodactyl and the passenger pigeon."
-Larry Niven
From
Man of Steel, Woman of Kleenex
I would recommend finding a copy and reading it. It's really short and it's available all over the web. Other
good things by Niven include:
For a Foggy Night, What Can You Say about Chocolate Covered Manhole Covers?, Cloak of Anarchy. All of these and more are also available in
N-Space by
Larry Niven which was published in 1990 and includes a forward by
Tom Clancy.
