I like the nostalgic quote of
"Nobody could understand the past except the people from it"
Very poignant to the older posters who have lost many friends and family of their youth.
Nostalgia is a very strange beast, usually drawn upon when you are sadened, the memories tend to be sorted into the happiest being remembered, the filing system of the mind tends to weed out the bad times, as they say nostalgia is a vice of the old.
We tend to forget the hardships of life economically and emotionally, many of us would not like to live as we did, there have been many advancements to make life more interesting for those of us who have a diminishing social life as we age, but youth is still pined for even when great hardship has been suffered.
I was listening to a political debate the other day and funnily enough someone talked about how political parties use nostalgia to gain votes, especially with the older generation, a hark back to the 'good old days', as such, it's a powerful tool.
I do agree that some people are particularly nostalgic or reminiscent about certain things or topics, mine is music, it can take me back to any era in my life, and the songs act like markers in my timeline. Others I know remenice of travels or certain meetings, social groups, I don't tend to miss some of the people too much but then again I still like meeting new people, always enjoy a new conversation.
People say don't look back too much as the happy thoughts can make you sad but I think that is part and parcel of life, the memories, the knowlege, the understanding and I quite like actually being this age, I've found the similar aged women I meet or aknowledge in the street seem to be much more civilised to one another as they age, a certain unspoken respect for getting this far, a lessening of competitiveness and a return to some sort of female bonding without the interuption of men.
