Michael - this is brilliant, truly. So clever. My biology isn't great, but isn't the hippocampus some part of the brain relating to memory? Your poem suggests I may be right, or I have misunderstood it completely!
Absolutely excellent! Best acrostic I have read on this site.

Wow the way you have written this poem is really vivid in your illustration. I can see the smile upon his face and the thought provoking memories of this man. You described it so well.
P.S.
Your pets are cute!

Dear Michael,

An intelligent write and so poignant.
To lose our mind is the worst nightmare ever. If only people knew how closely related it is to eating meat and dairy!
When the arteries to the brain are clogged up by saturated fats, out go the lights;)
Well done,

(((hugs)))
