When the market crashed in 2008, we moved into an area that was almost entirely inhabited by retirees in their 60's-80's. It was a life changing experience for the better. We were in our 40's then and had the maturity to appreciate those older than us than in our youth. Their wisdom, life experiences, the learning from their money and life mistakes and successes. It opened us up to an entirely new world. We befriend them lovingly and carefully, listening and watching for what it's like to be in the final stages of life. We have gained an incredible understanding of the challenges of aging that we otherwise never would have. For example, Mobility and Cognition issues can come on very suddenly - seems to hit around late 60's to early 70's where we observe it becomes challenging just to move and get around - even those who where well fit, go the gym every day, eat well, etc. We now have many Widows on our block, all the fellas are moving on before their wives. It's amazing how many it took by surprise where there was no estate planning, savings, etc and the wives thought that social security would be enough to take care of them for life. Imagine their shock and then being too old to go back to work or really struggling with it. It has been an enriching experience. I would challenge all of those younger to get involved in communities that span the ages...it's a wonderful thing to watch the cycles of life from beginning to end in an entire community - being a part of it, helping it, learning from it, and giving back to it.
