I totally get the brain cell thing as I see my own are diminishing rather quickly. I have a box of garden tags and an awesome computer label maker screaming for my attention. I need to get those markers out before I forget all my plants in my own yard! The road game keeps me sharp albeit a little dangerous on the road.
But the priority here is not to ever forget my plants! I want the names etched into my brain so that whenever Alzheimer's hits or a stroke, plant names are the ones I want to remember. After my kids and husband, of course!
I want to become that Crazy Old Lady Who Talks Incessantly About Plants.
