Is this something that happens inevitably at a certain age?
My mum was 80 recently so I had a good sort through some (old style printed) photos to find some of her over the years.
It left me feeling just a bit sad and melancholic- seeing how much she'd aged, especially over the last few years; seeing how much I'd aged (and DH) and how fab I looked when I was younger and didn't realise it; pictures of EXs; loved ones who are no longer with us
Now photos are digital I think we see older ones more often - they pop up as memories and people share them etc. Don't think it will be such a shock, for want of a better word, in the future as we'll look at them more frequently and not notice the passing of time so much.
