I read somewhere that the things that you are passionate about as a child, stay with you for life. They say it is similar to buying a computer: when young, the things you become passionate about go onto your hard drive, as you age and your tastes alter it is similar to buying software, but the hard disk info remains.
With me this is oh so true - images, aromas, sounds take me immediately back to an earlier time, the music, for example, of my early teens may not be great music, but oh does it affect me still! I only have to hear the opening bars of Daydream Believer by the Monkees, and I am back, 12 years of age, and all that it implies. I re-read books that I loved as a youngster, it is I accept a strange mix, Jennings is in there, as growing up on a council estate the tales of public school life fascinated me. How I longed for tuck boxes and dormitory life, tales of Nelson's time with Alexander Kent, the Bolitho novels' tales of sailing the seven seas held me in their sway, but there were also tales of The Man from Uncle mixed up with Gerald Durrell's weird family and love of animals.
