We are continually learning about the wonders of the brain, its ability to programme our bodies, adjudicate on complex situations, and indeed, look after our wellbeing. The brain is continually striving for things to do and the more challenged it is the better it functions. However, the converse is also true. The less our brains are challenged, the more idle they are, the less match fit they become, and their ability to function is reduced. This is particularly the case when people retire from work and their daily tasks no longer exist. The short-term memory or hippocampus is less able to store names, events, and other things we rely on each day.

Accordingly, as we age, we need to continue to exercise our brains as well as the rest about body. Exercise helps to flush blood through the brain, which is fundamentally and functionally a good thing. However, we also need to stimulate the brain with tasks, which might include crossword puzzles, sudoku, bridge, and other activities that challenge our mind. Learning a foreign language or a musical instrument is challenging at any time and more challenging for older persons. However, they are strong intellectual pursuits that stimulate the brain and can give a lot of pleasure. Brain training is not something that we should start late in life or in retirement. Rather than brain training late in life, may I suggest the term, lifetime learning, which is the process where we are continually pursuing new activities that challenge our intellectual parameters. 

In summary, when we think about successful ageing, activities and intellectual pursuits for the brain is essential. If we have adopted the approach of lifetime learning, then we are familiar with different intellectual challenges. If we are suddenly a retired person or someone without intellectual pursuits, it is essential that you identify intellectual challenges that you enjoy and perhaps can pursue with a friend. There are numerous opportunities to pursue, you just need to decide to pursue them.
