I am reading a book "Touching My Father's Soul" by Jamling Tenzing Norgay. His father was the first on the summit of Mt. Everest with Edmund Hillary. It is a delightful book to read. Jamling was on the IMAX climb where the movie was filmed....in 1996 I believe...and where the deaths described in "Into Thin Air" occurred....

He talks about some really noteworthy things..such as...The top of Mt. Everest has 1/3 the oxygen as at sea level. Sherpas have a special gene...It is believed. At 6 to 7000 feet, their bodies are equivalent to ours at sea level in terms of O2 needs. Sleeping with ones feet pointing towards the mountain is unlucky and disrespectful.

More later......
