Very early in my career I was provided with some very sage advice, “Everyone prepares for retirement financial but you also have to plan for it psychologically”. One the many benefits of our hobby is that it causes the further development of neuronal networks. We can look at our creations and immediately consider something we can do differently or problem solve a situation. We can begin a new layout from start to almost finished. We can read related material and pose and respond to questions on the forum. It all helps to keep the brain working. So, by working on our layouts, investigating new purchases, handling the transactions, discussing possibilities, etc. in reality we are protecting, and enhancing, our cognitive abilities.
