When we were in the US, we were trying to remember the names of some places in Accra where we went all the time. Even though we had been home for only a few months, we could not remember them! We talked about it several times. We even tried to use memory helps like imagining we were there; no luck.
The day after arriving in Accra, still tired and suffering the effects of jet lag, I just blurted out the names of those places without trying.
I meet a lot of Africans when I travel. Then a few weeks or a month later I might meet one of them in a different place than where I met them. I know that I know the person, but I cannot think of their name, nor where I met them. Back in the place where I met the person, I might at least have a chance of remembering their name.
Apparently, my brain is divided into compartments. All the information for a specific place goes into that compartment and I can’t access it unless I am in that place. Although, even then there is no guarantee.
