Here is a question about this article: A UCLA research study published in the June 2006 issue of the American Journal of Geriatric Psychiatry found that people can improve cognitive function and brain efficiency through simple lifestyle changes such as incorporating memory exercises, healthy eating, physical fitness and stress reduction into their daily lives. This study examined 17 subjects, (average age 53) with normal memory performance. Eight subjects were asked to follow a "brain healthy" diet, relaxation, physical, and mental exercise (brain teasers and verbal memory training techniques). After 14 days, they showed greater word fluency (not memory) compared to their baseline performance. No long term follow up was conducted, it is therefore unclear if this intervention has lasting effects on memory.
What is the answer to this question: Can one increase their brain efficency?
****
So... people can improve cognitive function and brain efficiency

Here is a question about this article: Gorton maintained good relations with the United States and Britain, but pursued closer ties with Asia. The Gorton government experienced a decline in voter support at the 1969 election. State Liberal leaders saw his policies as too Centralist, while other Liberals didn't like his personal behaviour. In 1971, Defence Minister Malcolm Fraser, resigned and said Gorton was "not fit to hold the great office of Prime Minister". In a vote on the leadership the Liberal Party split 50/50, and although this was insufficient to remove him as the leader, Gorton decided this was also insufficient support for him, and he resigned.
What is the answer to this question: Which countries did Gorton maintain close relationships with?
****
So...
United States and Britain
