    1. According to Eschwege, the total produce of the Brazilian diamond mines for the eighty years, ending in 1823, had not realised the price of one-and-a-half years’ average produce of the sugar and coffee plantations of the same country, although the diamonds cost much more labour, and therefore represented more value.

      Diamonds were first discovered in Brazil in 1729 near the city of Belo Horizonte. This started a diamond rush and a period of feverish migration of workers.

      Major diamond rushes also took place in the late 19th and early 20th centuries in South Africa and South-West Africa.

      Diamond rushes, like gold rushes or other types of rushes, are for Marx economic bubbles or asset bubbles (sometimes referred to today as speculative bubbles, market bubbles, price bubbles, financial bubbles, speculative manias, or balloons).

    1. Supposedly, Tianeptine, in contrast to other anti-depressants, stimulates release of neurotransmitter dopamine in nucleus Accumbens, that probably determine addictive potential of this drug.

      This potentially explains why tianeptine gives me energy. I've seen several other anecdotal reports as well. However, I've never taken illicit or prescription opioids, so I don't have a proper mode of comparison.

    1. Acidic pH

      Wonder if this is true in marine mammals, fish, worms that live in various environments. Am thinking with an evolutionary and developmental hat on. Just idle musing, wonder from a developmental perspective why acid and not alkaline (I think most soaps are alkaline) - mechanisms that differentiate breakoff points in the tree of life might be fun to learn about - to look smart.
