One hundred seventy years ago, tuberculosis was a lethal disease. This illness posed a significant threat to humanity, resulting in an estimated 1 billion deaths between 1700 and 1900. Notably, traces of tuberculosis have been found in the mummies of ancient Egyptian kings. In the late 1840s, German botanist Hermann Brehmer, confronted with the fatality of tuberculosis, relocated to the Himalayas in search of fresh air.

Even with the invention of high technology, if nothing is consensus, nothing benefits. - Joseph's "just my thoughts"
