If such a thing were possible, how many of us would then stop seeking new experiences in the future, instead preferring to relive previous ones from the past in the here and now? Never mind going to the dancing on week-ends and trying to chat up some brash, drunken nymphet - you could re-experience that night sixteen years back when you pulled the best looking girl at the work's dance and got up to some hanky-panky in a stationery cupboard. You could read again any comic you ever had as a child, faithfully recreated from your memory-banks for you to peruse any time you felt like it.
Deceased friends and relatives could be 'resurrected', and once again you could sit and converse with them just as you did when they were alive. Any conversation, any kiss, any holiday, any vanished toyshop from childhood could once more be as real to you as it used to be in bygone years. What's more, in your mind, you'd be the same age that you were when any incident you wish to relive first happened. You could spend a day as a seven year old, with all the vitality and enthusiasm that was yours when you were that age.
