Try a New Recipe

Without new and interesting experiences our brains get bored and lazy. One way to introduce some novelty [ For more on 'novelty' go here: http://www.braingle.com/mind/351.html ] into your lives is to try new foods. The sense of taste is an underused sense [ For more on 'underused sense' go here: http://www.braingle.com/mind/354.html ] that has a large capacity to trigger old memories. One bite of your grandmother's apple pie might bring back dozens of childhood experiences.

Instead of having your normal everyday breakfast, try something completely new. If you always have cereal, have eggs instead. If you cook at home, try to incorporate one new recipe each week. When you are at the grocery store grab one item off the shelf that you have never had before and take it home for a taste-test. If you eat out or order in, branch out and try a new restaurant or order something from the menu that you have never had before. If you never try new things, you'll never know if you are missing out on something that you really like. The new tastes and smells will help form new memories and may even remind you of something long forgotten.
