I think everyone intuitively understands this too. If you spend the next 3 months sitting in your boring office job that you've done 1000 days before, those 3 months may disappear entirely from your memory. Compared to taking the next 3 months and traveling to some strange land far away from home, and I bet those 3 months will stick out in your mind until your dying days.
It really does not work like that, you start mixing everything and everyone up in a depressing blob after a while.
I can't even remember the names of people i thought I loved or at least cared about.
Compared with my last five years in a serious, committed relationship, its a night and day difference.
To the next five years, and the ten after that hopefully.
