After several days of sleep patterns similar to those followed by night workers - three days of night shifts with only four to five hours sleep in 24 hours - the mice lost 25% of the brain cells, in part of the brain stem.

In 1996, after a 17-year career in the destination marketing industry, where I gained national standing as the CEO of the Convention & Visitors Association of Lane County, I was recruited by the founders of a new professional basketball league for women. The American Basketball League (ABL) hoped to leverage the success of the 1996 USA women’s national team at the Atlanta Olympics — much like USA Soccer is now leveraging the U.S. Women’s National Team’s victory in the World Cup.
