AN UNUSUAL YET USEFUL ACTIVITY
As I have previously mentioned, I had no idea that I had HSAM (Highly Superior Autobiographical Memory) until I was diagnosed with it at 23 years old; nor did I know that the condition even existed until I was 21 years old. It was my firm belief that every person thought, felt and remembered in exactly the same way as I do.
Yet regardless of whether I knew about my style of memory being somewhat rare or not, there was always an activity (which I now know to be related to my HSAM) that I enjoyed doing since I was a preteen.
