The brain is a funny thing. It requires constant stimulation and exercise to operate at its peak level. New experiences require it to work. New tastes, new smells, new sights, but those are often an expensive form of brain training. One cannot always fly off to another country at the drop of a hat or go to the latest source of haute cuisine. One thing the average person can do is learn or read. From childhood people are told to ,”Never stop learning.Is this new to you? Catch up here” With the internet, there is a wealth of information available for free. Anything of interest can be thoroughly researched from the comfort of a couch.
Learn something new everyday, whether that is a new word or how to trade stocks. It is important to apply yourself to expanding your knowledge every day. It is the single most important ingredient in the healthy brain cocktail. All the vitamin supplements in the world will not replace actively using your brain on a daily basis. Learning and applying new ideas and concepts get those synapses firing and form new paths, not to mention making you a more interesting person. Pick a and interesting topic and apply yourself to learning all you can about it.
