(A)The relationships between age and brain activity are well documented in neurologicalresearch. Although human brain plays a significant role in how we think, behave, and interactwith the world, our cognitive functioning can start to deteriorate as early as 40, (61) theage of 40 is a critical turning point for cognition. To be specific, according to Dr. ColinMcKenzie, professor of economics in Keio University, most people become less capable ofprocessing and memorizing information when they reach the age of 40. In addition to age, research has also found that a number of factors can influence ourbrain activity. For example, an Australian research team based in the Melbourne Institute ofApplied Economic and Social Research discovered that full-time work and brain function wererelated. They suggested that, for people over the age of 40, the (62) amount of worktime for their cognition is twenty-five hours a week, which can keep the brain (63) .While working excessively long hours can impair their mind and body, working less than thatamount of time can be harmful to their cognitive agility too. The study by Professor KarlEricsson at Florida State University also showed that expert performers spent around 21 to 35hours of practice time a week. However, Professor Ericsson’s study was not limited to aparticular age group, but focused on behaviors that can drive effective performances. Althoughthe (64) that twenty-five hours is the best for people over 40 still needs furtherinvestigation, it provides important information for companies that are planning to raise worktime.
