A number of studies have revealed a "positivity shift" with aging; whereas young adults are more likely to remember negative information than positive or neutral information, older adults may be at least as likely (or even more likely) to remember positive information compared with negative information. It has been proposed that this "positivity shift" may occur because older adults put more emphasis on emotion regulation goals than do young adults, with older adults having a greater motivation to derive emotional meaning from life and to maintain positive affect. In the service of these goals, older adults may focus their attention on things that will elicit pleasant feelings and may process positive information in a more self-referential fashion.

In order to let the contacts of our platinum sponsor enjoy the discount they deserve we extended the Happy Worm registration with a month. The sponsor deal and planning were made based on the fact that people could register themselves for the Happy Worm fee that initially ended the 5th of July.
