This article that I found is inspired by my mother because she is
always staying up to date on what keeps you mentally healthy and
active. Most of these top 10 are self explanatory and can be used for
someone of any age, not just someone 65+ which is usually what
articles of this nature tend to focus their attention towards. Enjoy!
