I'm 50 now and deliver cloud training. The discipline of passing one or two more difficult tech certifications a year gets my brain pumping. It's surprising what information the brain can store. When studying intensely I do 45 minutes study, 15 minutes rest. I have also observed anecdotally that information gets consolidated in your brain overnight. Finally, I have also observed some people have exceptional memories, like my wife. She is just wired better than me in this regard. My stance is to look after what you got, not worry about comparison too much.
