I think as we get older it's a way of re-living some happy times particularly in your childhood. Having lost my dad and all my grandparents now I like to remember the holidays when they were all with us. I try to explain to my children life without mobiles, computers, only 3 t.v. channels, they can't imagine it and think it must have been so boring - but it wasn't. Didn't know any different did we? At a very young age I remember roaming woods and fields on my own, the dangers were there but it is something I would never let my young children do now.
