Mother Nature is Cleaning up the Gene Pool?

There's been some interesting medical news lately. First came the study that showed a strong correlation between cigarette smoking and erectile dysfunction. Then came the news that Viagra impaired male fertility by making it more difficult for sperm to penetrate the egg to fertilize it. Sounds good to me--if you're stupid enough to smoke and then take Viagra to counteract the ED effects of the cigarettes, maybe you shouldn't be passing your genes on to the next generation.
