I wonder if in future this development will be seen as being of comparable importance to birth control pills?

Ten years ago this month the lives of millions of men and women were changed almost overnight by the advent of a little blue pill -- the first oral treatment for impotence . . . developed by accident by scientists at Pfizer Laboratories, was first approved for use by the US Food and Drug Administration on March 27, 1998.

I'd like to try some. It is said that it makes good wood better, as a sort of off-label use.
