When it comes to diversity, I am optimistic that at some point the rise of enlightened younger executives will trigger a sudden change of attitude in the boardroom.

The fact is, Hon Lik is not the first person to invent the e-cigarette. Way back in 1963, Herbert Gilbert made the world's first device that could be used to inhale tobacco-flavored air. In Gilbert's original version, there was no form of combustion and it was free of nicotine. He later designed a prototype that used a battery to create heat. He also used different flavors of water to create steam. He presented his prototypes to different chemical, pharmaceutical, and tobacco companies, but they simply turned down his prototypes.

The study participants asked to imagine acting out the trait, which is a method of self-imagining, were most successful in remembering the personality traits when questioned about them later. In fact, study participants who engaged in self-imagining were three times as likely to successfully remember a personality trait than participants who didn't use any type of memory device or method. The scientists in charge of the study believe that self-imagining could help individuals in rehabilitation programs, as well as anyone with a memory impairment. However, it's likely that the technique could help just about everyone, even if he or she wasn't currently in a rehabilitation program or diagnosed with memory problems. For example, if you wanted to remember where a friend bought a pair of shoes, you might imagine yourself walking into that store to buy the shoes.
