HIV is a simple demonstration that we don't have the political will to deal with a communicable disease that can not be cured. West Nile virus was allowed to become endemic in North America because we're still laboring under the false claims of Rachel Carson about DDT. Millions are dead of malaria because of her big lie. As a child, I used to run through the fog disbursed by the mosquito control trucks in Hawaii. It was DDT. My wife the the same. We're both just fine.
I am old enough to have the same childhood DDT-fog experience as you and your wife. It was a good time to be a child.
Now these very same parks I used to play in are unusable. They have been taken over by mosquitoes. And disease is spreading. Oh, but the politicians spend serious tax dollars on ineffective chemicals.
Thank you stupid voters and gutless politicians (another blood-sucking creature).
