Natural resource which made Ghana a prosperous kingdom is gold. This country had abundance of gold, since it literally sat on the gold mine, and its rulers used it for many years of successful trading. Therefore, the kingdom became powerful and prosperous. In some periods even dogs in Ghana had golden collars, and Ghana's kings were among the richest men in the world. They traded gold for salt (mostly with Arabs) which was very important for people's health. Today, Ghana is the second largest gold producer in Africa.
Aidan suffers from "anterograde amnesia".
Anterograde amnesia is lost the capacity to make new recollections after the occasion that caused the amnesia, prompting an incomplete or finish failure to review the ongoing past, while long haul recollections from before the occasion stay unblemished.

To a vast degree, anterograde amnesia remains a puzzling disease in light of the fact that the exact component of putting away recollections isn't yet surely knew, in spite of the fact that it is realized that the locales included are sure destinations in the fleeting cortex, particularly in the hippocampus and close-by subcortical areas.
