  1. And then you have to think that the uranium we mine today actually comes from ancient natural reactors partly, and those formed, and the by-products stayed close, so that literally a billion years later, they are still close enough that you can mine the uranium out of Oklo, and find evidence of these old natural reactors around, still where they were originally. no containment, and with water percolating through the rock as well. Most mines where you got the ore out, are good places to place the waste in, seeing as the stuff has been there long already without dispersal. Just fill it up, close off and leave it, and in a couple of centuries come back and mine it again.

  2.  @TheRealQuickSilver  The waste here does degrade over time, turning into other useful radioactive products along the way to becoming reasonably inert lead, so you just have to wait for it to cool to separate them out for re use in another reactor or for another use.

  3. Good reason to have the shots for all your pets, so next year my cat will once again be unhappy at going to the vet for the annual service, where the vet will shove a thermometer where the sun rarely shines, feel the rest, and then stick with a needle twice, as parvo virus is also bad.

  4. South Africa, where it is the most common thing that kills you if you have any other disease. If you are HIV positive it is more than likely you will also get TB, and thus your ARV pack for the month will include as well a cocktail of 4 to 6 TB drugs as well, because the most common strains are already multi drug resistant, and thus need a combination of all the cheap TB drugs to control it. the drugs are free in the public health service, and they are, as generics due to being so old, available from multiple suppliers as well, and cost less than a dollar for an entire month's supply. Biggest issue is that 6 month treatment cycle, where the patient often feels better after 3 months, then stops taking the medication, because it has some side effects that are not great, and thus a year later on comes back with MDR, and then does not respond well to the common drugs, and thus will either be permanently disabled, or dead within a year.

  5. Handprint is the artist saying "I was the one who did this picture, remember me for this", and drawing pictures of the prey is there to remind the spirit beings that the animals are revered, because they provide food, and thus deserve to be remembered for this.
