Another question for many would be Do we want to have more vivid memorys?
If this were possible the applications could be countless, yet it would very much be a double edged sword. Personally one I would take up without hesitation. The more you feel, the more you live, whether good or bad.
But of course I'm lucky, I don't have too many memory's that could slice into my psyche and wrap it in constant agony, thankfully. For many, they don't have such luck and thus would probably feel different.
That's actually a very interesting question. I would definitely want to have more vivid images too, but I get what you are saying, and I agree. Some people would just hate the idea of going back to a place that made them feel bad, or even miserable.
As I said, it's not only positive memories that come back, but I feel like it would be interesting to research more about it.
Definitely a topic we should learn more about, that's for sure.
These questions remind me of the condition of hyperthymesia. I recall watching the special on 60 minutes on the topic and the parents of a child with the condition reported their son recalled being scolded on a given date years prior and commented on the potential sadness those situations created. Those situations must be very tough, as a child has difficulty understanding at the time, however hopefully these people can apply their memories to using the past to better inform their futures.
