and, speaking of memories, sometimes deeply ingrained memories can conjure up the accompanying smells; it seems that our brains are able to go well beyond the video range of information, but we also store the smells and impressions of important events for future "replay".
e.g. the "event" of your first lover; can you not smell her/him?
and do not related olfactory experiences trigger the memory?
The smell of a baby's hair, freshly washed with baby shampoo
Fresh basil growing in the garden
Real Christmas trees
Coconut oil on the beach
Coffee
Cinnamon
Chocolate
Citrus
Salt air/The ocean
New cut grass
Roses
Lavender
Libraries, used book shops, old books
Clay
Fire burning in chimneys during the winter
Snow (I know this isn't scientific but perhaps a psychological thing)
ah yes, for a Canadian, there's nothing quite like the smell of fresh mown "snow"
I like that new-book smell.
The paper has to be the glossy type. I open the book (anywhere) and just stick my nose in close to inhale .... ahh, delightful!
