Discussing this with a friend today. I grew up in London 1980s and every summer holiday as a child we’d go to Leyesdown. I clearly remember the smell of the sea, it smelt strongly of salt. I have been to Hastings and Cambersands recently and that salty smell has gone, my friend (who hasn’t been to the beach) thinks I must be losing my sense of smell, maybe I am.. Why else would the smell have changed, anyone else noticed this?
