Thanks for suggesting L-theanine. The robot missed that one. Medications are the only things that interest me in this debate. Too bad Biden can’t be candid. It would be a real public service to inform all the aging Baby Boomers how to be mentally sharper.
Green Tea?
Yes, the L-theanine needs to be combined with caffeine or it would act as a mild anti-anxiety drug with no stimulative function.
I do not have dementiaš but the two together definitely enhance performance.
