Wow ! What is Hidden

We get the Smithsonian channel on satellite.
Last night , the segment was on the topic of the origin of AIDS.
Prior to the show last night , my answer would have been - Africa , somewhere in the middle , circa 1975 - 85.
Yes , would be the general response , sounds reasonable.
Nope.
Try 1908 or so.
The virus can be traced to a forest site in northern Cameroon and a monkey tribe. This forest location is over a thousand miles from the city of Kinshasha , where it is believed the AIDS virus started its trek around the world.
But 1908 ?
The monkeys passed the virus to humans
At that time , natives were used as porters by the French and British
commercial interests. Forced to cover long distances , in less than sanitary conditions , their camps were breeding places for disease transmission.
As well , the native women were used in makeshift brothels by the Europeans and the siphyllis and venereal disease organisms brought by the Europeans resulted in open sores and a mechanism for easy AIDS infection in the porter population.
The disease worked its way south to relatively modern Kinshasha w/  international connections - the AIDS epidemic was born.

The weather is fine. Slight chance of rain overnight. Temperatures warm , UV index is high.

Thus , everything you didn't know about AIDS - and still don't want to know

What is round on the ends and high in the middle ?
Thnx for Mon and Tues
