Radio 4 aired a programme on the role of smell in memory this week.
I was reminded of it last night.
Apparently a smell from your past ( that's an odd phrase) can trigger an intense burst of memory from a specific and generally unused part of the brain. The longer the period since you have " smelled the smell" the more intense the memory flash will be.
It's an interesting concept.
A mixture of cold cream and old fashioned face powder ( from one of those compacts) will always hurtle my brain back to my1970s Grandmother.
The smell of butterscotch angel delight to my primary school days
And a wiff of tequila.....well the very wiff of the bloody stuff takes me back to a 1990 house party in Bottesford Leicestershire where I experienced the very worst hangover in my entire life.
