And one other thought - when remembering lots of dates how do you remember what the date represents? E.g. I read another post where they said they remember Darwin released Origin of the Species in 1859 by thinking of bugs (their image for 59) crawling out of his beard.
However, that could get confusing if you also want to remember his date of birth, death and any other notable event.
So I wondered whether it was also worth having a modifier to add to the image to indicate if the date was a birth, death, the date they came to or left office, or ‘other’. So you could decide to add water to the image to indicate birth, fire to the image to indicate death, etc.
Does anyone do anything like that?
