As you get older you tend to stick to your ways and don’t bother with much of what is new. Is it true that we can’t teach an old person new tricks? Certainly not but we must be predisposed not to act this way.
One of the easiest way to keep your mind alert and going is to read non-fiction. When you read fiction you are indulging in a healthier hobby than screentime. Usually the new things you could learn from this are not many. Instead non-fiction is always based on someone’s perspective, and if you take that in you will definitely learn something.
There will be new technology every single day. In fact books can be delivered electronically or even via audio. But ultimately it is the content and intent of the authors that can help keep you abreast. For our bodies will likely wither faster than our minds.
