FDA checking reports Viagra causing blindness

Man, there they go scaring my willy off again! There could suddenly be lots of blind guys running (groping) around out there if this becomes an epidemic.
 
I would be more concerned using it with a heart condition than the fear of blindness. Statistically, it might happen, but not many cases have occured compared to the number of times the drug has been used. I would say it is still a pretty safe substance. The one time I tried it I choked on the pill, unfortunately the only thing I got was a stiff neck. :p
