"a recent Chinese study links nostalgia with a psychological state called "resilience" which is basically our ability to cope with life's little knocks. It found that people with resilience use nostalgia as a coping strategy."
When I was a little girl, I was given a lovely lockable diary. Recollecting the exact details is difficult - its puffy white cover with a pretty water colour illustration and elements of gilded gold - a little girl, perhaps a straw hat and puppy dog too. It was filled with lined pages of various pastel shades, and the pages emitted a gorgeous girlie scent. I cannot begin to describe the exact smell, but whenever I encounter it, I am immediately reminded of my special diary - and the smell of secrets. The safety contained in the writing on these pages was eventually lost to paranoid teenage years - but the smell always takes me back to a time when things were simpler.
