Just a tip I discovered for those “chronologically challenged”.
I’m 53 now. I started to notice more and more brain fog, confusion, etc.
What I’ve started to do is to take 24 oz of water with a hint of electrolyte first thing in the morning. Holy crap did that make a difference to my alertness. Like going from a 40 watt light bulb to a 100 watt. Even more than coffee.
I researched it after and found that aging people are more sensitive to mental alertness associated to dehydration.
While I am sure this is a “duh” for some, it was a very good reminder to me and also calling it out to us older guys/gals as particularly important.
