Studying the YouTube videos on neuroscience has taught me that sugar and stress are a big part of memory loss. Sometimes undiagnosed ADD is a factor too. The brain shrinks as it ages; the sad facts we all face. I am 75 and in watching others have decided that I will accept how well my brain works, rather than unwell and don't beat up on myself or my almost 80-year-old husband when we don't act like our once efficient, productive selves. We re-align ourselves everyday in keeping anxiety at a minimum. Retirement helps us own our calendar activities instead of it owning us. In looking back, however, we would have eaten minimal sugar, more whole grains, and removed ourselves sooner from toxic people and situations with therapy assistance. The 50s can be a wonderful time in life to assess and come up with a more adaptive plan, more to one's need for better physical and mental health.
