Viagra thoughts

For no reason whatsoever, I was thinking about Viagra today. I had two
thoughts: 1) What would Plato have thought of Viagra? He seemed to look at
old age and freedom from sexual needs, desires, and abilities as a blessing.
It was something that let him free to pursue other more important affairs.
(He expresses these views in the very beginning of the Republic.) 2)
Has the Viagra industry been good for the environment? Has demand for all
these bizarre aphrodisiac gone down now that we have a pharmaceutical that
works? Are rhinoceros tusks and whale ambergris less desired, and thus
leaving poachers out of a job? That would be a nice side benefit. Has PETA
thanked pfizer?
