Going on a Yeti hunt: Sir Edmund Hillary and the 1960 - 1961 Silver Hut Expedition

13 April 2026

It all started in 1958 when Hillary and the British physiologist and mountaineer Griffith Pugh questioned whether Everest (29,031 ft or 8,848.86 m) could be climbed without supplemental oxygen, possibly achieving this by acclimatising at 20,000 ft for several months. Hillary surmised that the prolonged period required for acclimatisation meant that this trek would be far more costly than his first Everest climb. This was a fair assumption to make, as the expedition with which he made his first summit is said to have cost between £15,000 and £30,000, and took seven weeks to reach the summit, including leaving Kathmandu, and acclimatising over a period of weeks at multiple camps up the mountain. Cost was just one of several barriers to climbing Everest in the 1950s. By the time the Silver Hut Expedition set off, just 7 other people in 3 different expeditions had summited Everest between Hillary's first success and September 1960. Further, these expeditions are the only expeditions that are believed to have even occurred during this time. This time, Hillary estimated that this experiment could cost up to $120,000 USD.

1980: Colin Gardener and his neighbour Helena Bradley see a lioness near Gardener's home in Wellington. Which is notable because New Zealand has no indigenous big cats. A police search around the Meadowcrofts property turns up nothing. A few days later, Gardener and another neighbour, Maurice Bradley, catch another glimpse of the creature and determine that it is not a lioness but just an unusually big ex-domestic cat.

Anabolic steroids were in the news during the Commonwealth Games and Dr Michael Kennedy has been studying their use by athletes for the past ten years. His conclusion is that "anabolic steroids have no effect on aerobic sports, such as running and swimming, but may lead to a small improvement in the performance of trained weightlifters." He quotes a 1972 study that showed when athletes were given placebo and told they were steroids, they got stronger and trained harder.

A recent leading article in The New Zealand Medical Journal looked at Diet and Behaviour. Food intolerance was strongly associated with the mother's level of education. A little knowledge is a dangerous thing? As regards the putative link between sugar and problem behaviours the article says "'...it is just as likely that restless or aggressive children seek out more sugar as that sugar causes the inappropriate behaviour." The authors conclude "...it should be recognized that modification of a particular child's diet is almost always accompanied by changes in management."
