On the Big 3 since March 2025 plus Arikayce added 2 weeks ago after 4 months of still testing positive. I am 64 and still have excellent recall with names and memories (my friends say "like an elephant" lol). What works for me is I am a firm believer that brain health is directly related to gut health and mental health. If your lifestyle/dietary choices are not optimal, the brain will suffer as well. Just as in physical health, use it or lose it. There's many things you can do to stimulate brain cells and keep your mind sharp and clear; high energy exercise knocks it out of the park. Check out singles tennis, running, rock climbing, etc. My 87 yo dad can do these with me, in addition to shooting pool, Sudoku, NYT crossword, etc. Just do not sit in front of the TV. The goal is to encourage your brain cells to work!
