American coffee can be a pale solution served at a temperature of 100 degrees centigrade in plastic thermos cups, usually obligatory in railroad stations for purposes of genocide, whereas coffee made with an American percolator, such as you find in private houses or in humble luncheonettes, served with eggs and bacon, is delicious, fragrant, goes down like pure spring water, and afterwards causes severe palpitations, because one cup contains more caffeine than four espressos.
The human body cannot survive being in temperatures over 200 degrees centigrade for more than a few moments, especially in the fast moving current of a surge. Trying to breathe in the dense cloud of hot ash in the absence of oxygen would lead to unconsciousness in a few breaths, as well as causing severe burns to the respiratory tract... On the other hand, survival is possible in the more distal parts of a surge if there is adequate shelter to protect against the surge flow and its high temperature, as well as the missiles (rocks, building materials) entrained in the moving cloud of material.

The name Kyirong means 'the village of happiness, ' and it really deserves the name. I shall never cease thinking of this place with yearning, and if I can choose where to pass the evening of my life, it will be in Kyirong. There I would build myself a house of red cedar wood and have one of the rushing mountain streams running through my garden, in which every kind of fruit would grow, for though its altitude is over 9, 000 feet, Kyirong lies on the twenty-eighth parallel. When we arrived in January the temperature was just below freezing it seldom falls below -10 degrees Centigrade. The seasons correspond to the Alps, but the vegetation is subtropical. Once can go skiing the whole year round, and in the summer there is a row of 20, 000-footers to climb.
What, after all, is so special about genes? The answer is that they are replicators. The laws of physics are supposed to be true all over the accessible universe. Are there any principles of biology which are likely to have similar universal validity? When astronauts voyage to distant planets and look for life, they can expect to find creatures too strange and unearthly for us to imagine. But is there anything which must be true of all life, wherever it is found, and whatever the basis of its chemistry? If forms of life exist whose chemistry is based on silicon rather than carbon, or ammonia rather than water, if creatures are discovered which boil to death at -100 degrees centigrade, if a form of life is found which is not based on chemistry at all, but on electronic reverberating circuits, will there still be any general principle which is true of all life? Obviously I do not know but, if I had to bet, I would put my money on one fundamental principle. This is the law that all life evolves by the differential survival of replicating entities. The gene, the DNA molecule, happens to be the replicating entity which prevails on our own planet. There may be others. If there are, provided certain conditions are met, they will almost inevitably tend to become the basis for an evolutionary process.
